In this regard, the system is required by production and manufacturing companies, human resources, and materials to be enhanced by scheduling and planning of production. In addressing this problem of scheduling over a mid-term possibility, material flow and production objectives should be forecast by solving the problems of planning. Only when the production planning problems have been solved then scheduling problems could be addressed. In this work, we relate scheduling with capacity planning in relation to the production of goods and services. Also reviewed the common problems associated with the industry and how they are overcome. 1 Introduction The production process is the combination of a good or service via the use of measurable input and immeasurable input here by generating output which has value for consumption through donating to individual efficacy [1]. Producing companies now have a new expansion direction due to the new trends of sustainable development, the increase in manufacturing efficiency, and the rapid development of industries [2]. The combination of product losses and processing yields makes up raw material efficiency. In and around a processing activity the amount of raw material lost makes it distinguished by the amount of yield used which are determined by technological characteristics of the process and can be achieved through production scheduling which is the scheduling of machines and operations [3]. Important parts of supply chain management are scheduling and Production planning, strategic and operational decisions are carried out at the boundary between operations and sales. For forthcoming periods (such as days or weeks), the inventory qualities and production are determined, sequencing of production quantities, timing, and the actual task assignments within those time periods are also determined [4]. Among many planning roles in the industrialized sector is Scheduling of operations, Due to interruptions or arrival of new information in the scheduling process, finding a schedule is only part of the whole system [5]. There is a need for rescheduling when current schedules are becoming worse or even possible. This rescheduling makes it difficult for capacity planning to be effective thereby breaking the bridge between the producer and the consumers [4]. Capacity planning is the process of meeting changing demands for its products by determining the production capacity needed by an organization without wasting resources through Forecast on how they are going to match what is required. In order tofulfill the requirements of a market these factors all impact each other, the capacity an operation can provide depends largely on the ability it has to evaluate the options it has either to decrease or increase it [6]. The outdated methods are becoming superseded due to the introduction of capacity planning causing a rise in a competitive environment which forces An Increasing number of Industrial companies to adapt to this method. Capacity planning involves the fluctuation of market cost leading to efficient adjustments, shorting delivery times, and Improves due date observation [7]. Material planning activities are the backbone of the planning process which are the input/output (I/O) control, master production scheduling (MPS), and MRP [7]. https://doi.org/10.1051/e3sconf/202130 E3S Web of Conferences 309, 01003 (2021) ICMED 2021 901003 © The Authors, published by EDP Sciences.
