INTRODUCTION

Contextualization of Halal Supply Chain Management

Halal supply chain management involves the various processes related to the production, handling, storage, and distribution of goods that meet halal standards as outlined by Islamic law. Halal standards cover a diverse array of products, including food, beverages, pharmaceuticals, and cosmetics, guaranteeing that they do not contain forbidden (haram) substances like pork and alcohol, while also adhering to particular ethical production practices (Omar et al., 2018). The rising global demand for halal products, especially in countries with large Muslim populations, has made the halal supply chain a crucial part of international trade, constituting a multi-billion-dollar industry (Mohammad & Ali, 2020).

The halal supply chain differs from traditional supply chain management in several important aspects. The certification process is one of the main distinctions. Halal certification is granted by religious organizations that confirm that products and processes comply with Islamic regulations (Ahmad et al., 2020). This certification guarantees that every phase, from obtaining raw materials to the finished product, adheres to the strict standards necessary for a product to be considered halal. Halal supply chains differ from traditional ones in that they must adhere to ethical sourcing guidelines, encompassing labor practices and animal welfare issues, which adds complexity to logistics and operations (Aziz et al., 2020).

Alongside these ethical and legal considerations, halal logistics necessitate particular practices to avoid contamination between halal and non-halal products. For instance, keeping storage areas and production facilities separate is essential to prevent cross-contamination (Karim et al., 2021). The logistical challenges involved add layers of complexity to scheduling and coordination, highlighting the need for focused attention and effective management strategies in the halal supply chain.

The Importance of Scheduling in Halal SCM

Scheduling in halal supply chain management is crucial for ensuring adherence to halal standards and preserving product integrity across the entire supply chain. Halal products, particularly in the food and pharmaceutical sectors, require careful attention to timing. The shelf life of halal-certified food products significantly influences demand planning and production scheduling (Ibrahim et al., 2024 and Sohail et al., 2020). Additionally, the halal slaughtering and processing of meat requires adherence to specific rituals and timelines, creating unique scheduling challenges that are distinct from conventional meat production (Akbar et al., 2019).

Another critical aspect of scheduling in halal SCM is the issue of traceability. Products in the halal supply chain must be traceable at every step, from raw materials to final distribution, to guarantee that they have not been contaminated or substituted with non-halal substances (Sarbani et al., 2024 and Khan & Rahman, 2020). Effective scheduling guarantees that accurate records are maintained, products are tracked, and halal standards are upheld throughout every phase. Without careful planning and monitoring, there is a chance of unintentionally breaching halal standards, which could result in expensive recalls or the loss of certification.

Furthermore, it is necessary to implement segregated storage to avoid the contamination of halal products with non-halal items. It is essential to implement careful planning for warehouse space and inventory management to maintain the separation of halal and non-halal items, thereby ensuring adherence to halal guidelines (Idris et al., 2024 and Aziz et al., 2020). Effective scheduling is essential for managing deliveries, production batches, and warehouse operations, ensuring that these segregation practices are adhered to promptly.

The ethical sourcing of halal products involves particular timelines and scheduling limitations. For instance, halal meat needs to come from slaughterhouses that adhere to Islamic ethical standards, which includes coordinating slaughtering times with religious practices like prayer times (Senathirajah et al., 2024 and Sohail et al., 2020). Moreover, it is crucial to manage time-sensitive processes such as packaging and distribution to guarantee that the final product adheres to halal compliance standards, especially for fresh or perishable goods (Karim et al., 2021).

An efficient planning in halal supply chain management guarantees adherence to religious, ethical, and logistical requirements, while reducing the chances of contamination and ensuring the prompt delivery of halal-certified goods. With the integration of halal supply chains into the global economy, there is a rising demand for specialized scheduling systems to effectively manage these complexities. The challenges associated with halal certification, segregation, traceability, and time-sensitive operations require tailored scheduling approaches to maintain the integrity of halal products in the marketplace.

LITERATURE REVIEW

Existing Research in Halal Supply Chain Management

Halal supply chain management is an expanding field of study, with research examining different elements like halal certification, logistics, and operational difficulties. Many researchers have pointed out the growing intricacy of halal supply chain management because of its connection to religious, cultural, and ethical considerations. The halal industry, especially in sectors like food, pharmaceuticals, and cosmetics, has emerged as a major global market (Toloie Eshlaghy et al., 2023, Osman et al., 2024 and Omar et al., 2018).

Nonetheless, overseeing the halal supply chain involves distinct challenges that set it apart from traditional supply chain management. A key challenge is making sure that halal standards are met at all points in the supply chain, starting from sourcing raw materials to delivering the final product (Khan & Rahman, 2020).

Specifically, maintaining the integrity of halal products necessitates keeping halal and non-halal items separate, which affects inventory management, storage, and transportation logistics (Aziz et al., 2020). Halal certification is an important aspect, as it requires that products and processes undergo inspection and approval by recognized religious authorities (Ahmad et al., 2020). Research indicates that adherence to halal certification influences not just product quality but also plays a significant role in consumer trust and brand reputation (Karim et al., 2021).

Various researchers have examined the ethical sourcing standards in halal supply chain management, focusing on the humane treatment of animals in halal meat production and the ethical practices involved in labor sourcing (Sohail et al., 2020). The ethical aspects require more careful examination and adaptable scheduling to make sure that production timelines are in harmony with religious practices and labor regulations (Karim et al., 2021). Additionally, the urgent nature of halal products, including fresh food items and pharmaceuticals, necessitates careful planning to prevent spoilage and maintain halal certification (Akbar et al., 2019).

Scheduling Models in Halal Supply Chain Management

Traditional supply chain management employs different scheduling models to enhance production, reduce costs, and boost efficiency. Some typical approaches are linear programming (LP), heuristic algorithms, and genetic algorithms (GA). Linear programming is commonly applied to address resource allocation and scheduling issues in conventional supply chains, enabling the optimization of production schedules while considering constraints like time, capacity, and demand (Baker & Trietsch, 2018). Heuristic methods like the Earliest Due Date (EDD) and Shortest Processing Time (SPT) rules are frequently used for straightforward scheduling challenges (Pinedo, 2016). Genetic algorithms, inspired by evolutionary biology, are utilized to enhance complex scheduling challenges by producing and refining viable solutions through several iterations (Zhang et al., 2017).

In halal supply chain management, it is essential to adapt or enhance traditional scheduling models to address the specific limitations that halal practices introduce. For instance, scheduling models need to take into account the separation in storage and production, requirements for traceability, and practices for ethical sourcing, aspects that are usually overlooked in traditional supply chain management models (Karim et al., 2021). For example, in halal food production, genetic algorithms might be employed to enhance production efficiency while adhering to the specific timeframes required for halal slaughtering, packaging, and delivery, influenced by operational limitations and religious practices (Akbar et al., 2019). In halal pharmaceutical supply chains, it’s important to consider the quick turnover of inventory in scheduling to make sure that products stay fresh and meet halal certification requirements (Sohail et al., 2020).

However, despite the application of these conventional models in halal SCM, there is a notable gap in the literature concerning specific halal scheduling models. Much of the current research tends to modify general supply chain management scheduling frameworks or addresses wide-ranging logistical challenges, but it often falls short of creating detailed models that consider halal-specific needs. There is a need for the creation of new algorithms and frameworks designed specifically for halal supply chain management that address these distinct challenges (Aziz et al., 2020). These models must consider factors such as religious time constraints (e.g., prayer times, fasting periods) and the alignment of production schedules with halal certification requirements (Khan & Rahman, 2020).

Regulatory and Compliance Factors

A crucial element of halal supply chain management is the regulatory framework, influenced by the necessity for halal certification and compliance with Islamic dietary regulations (Ahmad et al., 2020). These regulations impact both the production and distribution processes, requiring careful scheduling to ensure that halal standards are met at every stage of the supply chain. Typically, halal certification requires a third-party certifying organization to examine the facilities, review processes, and confirm that the products comply with halal standards (Karim et al., 2021). The certification process can take a considerable amount of time and should be factored into production timelines when planning.

Food products that are considered permissible must be produced and processed following particular guidelines, which include the exclusion of certain ingredients such as pork and alcohol. Furthermore, halal meat needs to be prepared following Islamic guidelines, which involve particular ritual methods and timing. It’s essential to plan these processes carefully to make sure we adhere to religious laws and prevent any delays or interruptions in the supply chain (Sohail et al., 2020).

Fair labor practices are also crucial in halal certification. Many halal certifying bodies require that workers involved in halal production follow specific ethical labor practices, which can impact scheduling in terms of workforce availability, working hours, and working conditions (Aziz et al., 2020). For example, facilities that process halal meat need to make sure their employees follow Islamic principles related to hygiene, conduct, and the humane treatment of animals (Sohail et al., 2020).

The intricate nature of halal certification and compliance necessitates that supply chain management systems incorporate regulatory requirements straight into their scheduling processes. Therefore, scheduling models in halal supply chain management should prioritize not just operational efficiency but also the timely adherence to all regulatory requirements (Omar et al., 2018). This calls for a thorough grasp of the operational demands of halal supply chains as well as the regulatory structures that oversee them.

HALAL-SPECIFIC SCHEDULING CHALLENGES

Time Sensitivity

Halal products, especially in the food and pharmaceutical sectors, typically come with stringent expiration dates because of their perishable qualities. When it comes to food, the shelf life of halal-certified products is an important factor, particularly with fresh ingredients such as meat or dairy (Akbar et al., 2019). The tight timelines create notable scheduling difficulties, as products need to be delivered while they are still fresh, maintaining both quality and adherence to halal standards. In the pharmaceutical sector, it is essential that halal-certified medications are produced, tested, and distributed within designated timeframes to guarantee their effectiveness and adherence to halal standards (Sohail et al., 2020).

It’s important for scheduling models to incorporate these time constraints into the production and distribution processes. For example, scheduling algorithms such as just-in-time (JIT) can be modified for halal supply chain management, where production is tightly synchronized with demand to reduce product waste and guarantee that products are delivered at the ideal time before they expire (Baker & Trietsch, 2018). Another approach could involve time-window scheduling, where each stage of production, from slaughtering to packaging, is assigned specific time slots to maintain freshness and compliance. This integration makes sure that time-sensitive products are handled properly, preventing spoilage and preserving halal integrity throughout the distribution process.

Segregation and Traceability

A key aspect of halal supply chains is ensuring that halal products remain uncontaminated by non-halal items. This involves separating materials, storage areas, and production lines to prevent any type of cross-contamination, especially during manufacturing, transportation, and warehousing (Khan & Rahman, 2020). In halal meat production, it’s essential for halal slaughterhouses to have equipment, utensils, and processing areas that are solely used for halal products. This practice helps to avoid any contamination from non-halal meat (Aziz et al., 2020).

The challenge in scheduling here is ensuring that these segregation protocols are followed without disruption to the overall supply chain flow. It is essential for scheduling methods to designate particular production times or spaces for halal and non-halal items to guarantee segregation throughout all stages of production. For example, blocking techniques can be used in scheduling to allocate specific production windows or resources for halal products (Pinedo, 2016). In a similar vein, sequencing models can help establish the sequence in which products are handled, making sure that halal products are prioritized or that machinery is thoroughly cleaned beforehand (Zhang et al., 2017).

Furthermore, traceability is a key concern in halal SCM, as consumers and regulators require evidence that products are indeed halal and have not been cross-contaminated during their journey through the supply chain. Scheduling systems should definitely incorporate traceability features to enable tracking of each product’s movement and status throughout every stage. Blockchain technology presents a promising approach to improve traceability in halal supply chains by securely documenting transactions and verifying product authenticity (Khan & Rahman, 2020). Models that incorporate blockchain data for scheduling could allow for immediate tracking and recording of product status, promoting both compliance and transparency.

Production Scheduling in Halal Meat Processing

In halal meat processing, it is crucial to carefully schedule specific time-sensitive activities like halal slaughtering, processing, and packaging to meet both religious and operational standards. Halal slaughtering involves adhering to Islamic law, which includes invoking the name of God (Bismillah) during the process and ensuring that animals are treated humanely. These procedures need to be completed within designated time frames, frequently aligned with religious practices like prayer times (Sohail et al., 2020).

Integrating halal-specific activities into broader production schedules presents scheduling challenges, particularly when halal meat processing facilities run alongside non-halal facilities or larger production operations. This integration typically requires the allocation of resources, such as specialized equipment and qualified personnel, while also ensuring that halal processes maintain the overall efficiency of the larger production system. For instance, allocating time slots can help ensure that slaughtering and processing activities take place during designated hours, minimizing the chances of delays and ensuring adherence to halal standards (Karim et al., 2021).

Moreover, in halal meat processing, it’s essential to take into account the timing of packaging and transportation to ensure the preservation of halal integrity. Given the high perishability of halal meat, it is crucial for the scheduling model to synchronize the processing, packaging, and transportation stages effectively to prevent any delays that might result in the product falling out of compliance (Akbar et al., 2019). Utilizing critical path methods (CPM) or PERT (Program Evaluation Review Technique) can be beneficial for managing these time-sensitive phases of production, making sure that every activity is finished within its assigned time frame (Pinedo, 2016).

The scheduling challenges specific to halal necessitate sophisticated models that can handle time sensitivity, segregation, traceability, and the distinct needs of halal meat processing. Incorporating these constraints into scheduling practices allows halal supply chains to meet both operational and religious standards, all while ensuring efficiency and maintaining product quality.

PROPOSED SCHEDULING MODELS

Hybrid Scheduling Techniques

In halal supply chain management, it’s essential for scheduling models to combine conventional optimization methods with unique halal-related requirements. A hybrid scheduling model integrates traditional supply chain management techniques, like linear programming, heuristics, and genetic algorithms, with elements specific to halal processes, including religious observances, halal production cycles, and the necessity for product segregation. These hybrid models tackle the intricate dynamics of halal supply chain management while making sure to adhere to religious, ethical, and operational standards.

For instance, genetic algorithms (GAs), commonly utilized in traditional supply chain management for optimization, can be modified to include halal-specific criteria. Genetic algorithms can create practical production schedules that take into account prayer times, religious holidays such as Ramadan, and fasting periods, all of which greatly influence labor availability and production timelines (Zhang et al., 2017).

Moreover, these algorithms can effectively separate halal and non-halal products in both storage and production settings, thereby preserving product integrity. Hybrid models can integrate heuristic rules for scheduling halal slaughtering and processing, providing flexibility and adjustments based on particular religious and cultural timings (Karim et al., 2021). By integrating both traditional scheduling techniques and halal-specific constraints, hybrid models offer a balanced solution that addresses operational efficiency and religious compliance.

Simulation-Based Approaches

Simulation-based methods provide important perspectives on the intricacies of scheduling in halal supply chain management by modeling and examining the dynamic interactions present within the supply chain. In halal supply chains, the choices made regarding scheduling can greatly influence product quality, shelf life, and the status of halal certification, especially for perishable items such as meat and pharmaceuticals. Simulation models enable individuals in charge to test various scheduling scenarios, offering a safe method to evaluate how particular production or transportation schedules influence overall supply chain performance. For example, discrete-event simulation (DES) models can replicate the movement of halal-certified products across different phases of production, storage, and transportation. These models can assist in pinpointing the optimal times for processing and delivering products to enhance shelf life while maintaining adherence to halal standards (Baker & Trietsch, 2018). A Monte Carlo simulation approach can effectively model the variability in production processes, including potential delays from equipment failure or labor shortages, and evaluate their effects on halal certification and product quality (Pinedo, 2016). Through the analysis of these simulations, managers in halal supply chain management can gain deeper insights into scheduling dynamics and create stronger strategies for handling time-sensitive products.

Case Studies or Examples

Case studies from the real world show how effective scheduling strategies can be applied in halal supply chains, highlighting the potential for enhanced operational efficiency while ensuring halal compliance. An example of this is the scheduling of halal meat processing in facilities that produce both halal and non-halal products. A halal-certified slaughterhouse in Malaysia implemented time-slot scheduling to ensure that halal and non-halal slaughtering occurred at different times throughout the day, thereby preventing contamination. The implementation of a hybrid scheduling model that merged block scheduling with separation rules and incorporated Islamic prayer times led to increased throughput while ensuring product integrity (Aziz et al., 2020).

In the halal pharmaceutical sector, a company in Indonesia implemented simulation-based scheduling to enhance production and packaging efficiency for halal-certified medications. The simulation model considered various variables, such as staff availability (impacted by prayer schedules) and regulatory inspections, to ensure that the production process remained within the required halal certification constraints (Sohail et al., 2020). Utilizing simulation contributed to less waste, enhanced efficiency, and lowered the chances of not adhering to halal guidelines.

Ayamas Food Corporation, a prominent halal-certified poultry processing company in Malaysia, exemplifies the importance of scheduling in halal food production.

Blockchain technology has become a game-changer in halal supply chain management, especially in improving traceability and transparency. In halal supply chains, it is crucial to guarantee the authenticity of products and to avoid contamination with non-halal materials. The decentralized and immutable characteristics of blockchain offer a perfect way to monitor the journey of halal products from their production to delivery. By recording every transaction in a secure, time-stamped ledger, blockchain enables real-time traceability, which is crucial for maintaining halal certification throughout the supply chain (Khan & Rahman, 2020).

The combination of IoT devices with blockchain enhances traceability by delivering real-time information about the conditions in which halal products are stored and transported. IoT sensors are capable of tracking various factors like temperature, humidity, and handling conditions, which helps maintain compliance with halal standards across the supply chain (Sohail et al., 2020). For instance, when it comes to halal meat processing, blockchain technology can trace the entire slaughter process of each animal, ensuring compliance with halal regulations. Meanwhile, IoT devices can oversee storage conditions to ensure the product stays uncontaminated.

When it comes to scheduling, blockchain and IoT technologies enhance accuracy and transparency by delivering real-time information on the status and location of products. This can assist in organizing production and transportation timelines more effectively, reducing delays, and avoiding bottlenecks. Moreover, these technologies can help confirm if halal products are being delivered on time, aiding supply chain managers in maintaining adherence to both operational and religious standards (Aziz et al., 2020).

Artificial Intelligence (AI) and Machine Learning (ML)

Artificial Intelligence (AI) and Machine Learning (ML) offer powerful tools for optimizing scheduling in halal supply chains, especially in predicting demand and adjusting production schedules accordingly. Algorithms in AI and ML can examine past data and consumer trends to predict demand patterns, assisting supply chain managers in refining production schedules and minimizing waste. This ability is especially beneficial in halal supply chain management, where timing is crucial for perishable items like fresh halal meat and pharmaceutical products (Baker & Trietsch, 2018).

For instance, models that utilize AI for demand forecasting can anticipate changes in the demand for halal products influenced by seasonal trends, cultural occasions (such as Ramadan), or specific geographic areas. These forecasts can help in developing flexible schedules that modify production and distribution on the fly, making sure that halal products are accessible when required without excess production, which might result in waste or spoilage (Sohail et al., 2020).

Machine learning algorithms can enhance the optimization of halal production cycles. These algorithms can consider different constraints, including halal certification requirements, religious observances (like prayer times), and the necessity for product segregation during manufacturing. Through ongoing analysis of previous scheduling choices and their results, machine learning models can forecast the most effective production timings and resource distributions, guaranteeing adherence to halal standards while reducing operational expenses (Zhang et al., 2017). Additionally, AI can facilitate the automation of adjustments in reaction to immediate shifts in demand or unexpected disruptions, thereby improving the responsiveness of the supply chain.

Regulatory bodies are increasingly incorporating stricter rules for halal certification, and these rules could have significant implications for how halal scheduling systems are designed and operated. Investigating the impact of shifts in Islamic dietary regulations or the international halal market on future scheduling strategies is essential, especially for multinational halal supply chains that must adhere to diverse local standards.

In conclusion, although there have been notable advancements in optimizing operational efficiency and adhering to religious guidelines within halal supply chain scheduling, further research is essential to tackle the distinct challenges encountered by these supply chains and to investigate innovative solutions that will influence the future of halal logistics.
