An Evaluation of Production Scheduling and Control in a Manufacturing Firm

1.0 Introduction

1.1 Background of Study

Historically, production scheduling and control have evolved from traditional manual systems to sophisticated digital solutions. The emergence of advanced manufacturing technologies, including Enterprise Resource Planning, Just-In-Time production, and Artificial Intelligence (AI)-driven scheduling, has significantly improved the efficiency and accuracy of manufacturing processes (Heizer & Render, 2019). Production scheduling and control play a crucial role in the manufacturing industry, ensuring that operations run smoothly, efficiently, and cost-effectively. As manufacturing firms strive to meet market demands, optimize resource utilization, and reduce lead times, the need for effective scheduling and control mechanisms has become increasingly vital (Stevenson, 2021). Production scheduling involves the systematic planning and organization of production activities to enhance efficiency, while production control ensures adherence to schedules and quality standards (Chase et al., 2020).

Nahmias & Olsen (2020) stated that effective production scheduling and control contribute to increased operational efficiency, reduced production costs, and improved product quality. Studies have shown that industries that implement well-structured scheduling and control systems experience lower production waste and higher profitability (Nahmias & Olsen, 2020). However, improper scheduling can lead to bottlenecks, delays, and resource underutilization, affecting the overall performance of a manufacturing firm (Krajewski et al., 2021).

According to Stevenson (2021), production scheduling refers to the process of organizing, controlling, and optimizing work and workloads in a manufacturing setting. It involves the allocation of raw materials, equipment, and human resources to maximize efficiency while meeting customer demands. Similarly, production control ensures that manufacturing processes adhere to planned schedules, minimizing delays and inefficiencies (Chase et al., 2020). In the highly competitive manufacturing industry, effective production scheduling and control contribute significantly to productivity, cost reduction, and customer satisfaction. Poor scheduling may result in production bottlenecks, resource wastage, and increased operational costs (Heizer & Render, 2019). Therefore, this study evaluates the effectiveness of production scheduling and control in a manufacturing industry, identifying challenges, best practices, and the impact on overall production performance.

1.2 Statement of Problems

Investigation revealed that many industries still rely on outdated scheduling methods that do not align with modern manufacturing demands. The lack of real-time data integration and automation further complicates production processes, resulting in inconsistent output and missed deadlines (Nahmias & Olsen, 2020).

Furthermore, production scheduling is often affected by external factors such as fluctuating market demand, material shortages, and regulatory constraints, which limit the efficiency of control mechanisms (Chase et al., 2020). It is against the backdrop that this study seeks to evaluate the effectiveness of production scheduling and control in a manufacturing industry.

Policymakers and business leaders will also find the study valuable in formulating strategies that promote sustainable and efficient production practices.

1.7 Scope of Study

This study will focus on the evaluation of production scheduling and control in a manufacturing industry, with a specific emphasis on Dangote Cement Plc, Obajana Plant, Kogi State, Nigeria. The study will be limited to the operations of Dangote Cement Plc, Obajana Plant, focusing on its production processes, workforce coordination, and management strategies.

Data will be collected from production managers, employees, and other key stakeholders involved in manufacturing operations. While the findings may be applicable to other industries, the study will specifically address challenges and solutions relevant to the Nigerian manufacturing context.

1.8 Limitations of the Study

During the course of this study, there were some problems encountered which stood as limitations to the research work. Some of the limitations include:

1. Time Constraint: The time frame given to accomplish this project was very short due to school academic calendar and it was carried out under pressure which made the researcher not to implement some necessary features.
2. Financial Constraint: Insufficient fund tends to impede the efficiency of the researcher in sourcing for the relevant materials, literature or information and in the process of data collection (internet, questionnaire and interview).
3. Initial Cooperation Delay from Respondents: A particular limitation of this work came as a result of the respondent refusal to offer their cooperation at the initial time they were contacted. This contributed in making the success of this research study difficult.

1.9 Definition of Terms

Production Scheduling: This refers to the process of planning and organizing manufacturing activities to ensure efficient use of resources, timely production, and minimal delays. It involves setting timelines for tasks, coordinating materials, and optimizing workflow to meet production goals (Nahmias & Olsen, 2015).

Production Control: This is the process of monitoring and regulating production activities to ensure that they align with planned schedules and quality standards. It includes tracking progress, adjusting schedules when necessary, and addressing any disruptions in the manufacturing process (Stevenson, 2020).

Manufacturing Industry: This refers to the sector that involves the production of goods using labor, machines, and raw materials. It encompasses industries such as automobile, cement, textiles, and food processing, among others, where production scheduling and control play a crucial role in operational efficiency (Heizer, Render, & Munson, 2019).

Efficiency in Manufacturing: Efficiency in manufacturing refers to the ability of a production system to minimize waste, optimize resources, and maximize output while maintaining quality standards. It is often measured in terms of productivity, cost-effectiveness, and adherence to schedules (Krajewski, Malhotra, & Ritzman, 2016).
