Introduction Of Manufacturing Scheduling Process Essay
â⬠2 Introduction Introduction to manufacturing scheduling In the real world, it is necessary for any manufacturing system, production system, even service system to create an effective schedule able to overcome any change that may happen in the environment in order to continue in the competitive world. Scheduling can be denoted as the process of assigning a set of activities to resources of finite capacity over limited time. Scheduling process aims to sequence the activities and states their releasing time on each machine to satisfy the desired performance criteria while considering the capacity and technological constraints[1]. Most of the manufacturing companies work on streamlining their production processes, meeting their customers requirements and accommodate the high variety of demands. Therefore, there was a big need for a job shop. Further, it is necessary to develop scheduling technique able to improve different objectives of scheduling such as makespan, machine utilization, meeting due dates, etc. Over the years, many methods were developed in seeking to improve scheduling processes such as hand-made scheduling, whiteboards, spreadsheets, and advanced methods. Hand-made scheduling was the spontaneous method that appeared in scheduling environment. First come first serve (FCFS) is an example of hand-made scheduling, it is usually used when the jobs don t affect on the main purposes of the company, or the jobs don t have a due date. Hand-made scheduling hasShow MoreRelatedDecision Support Tool For Dynamic Job Shop Scheduling785 Words à |à 4 PagesTOOL FOR DYNAMIC JOB SHOP SCHEDULING ATIKAH BINTI SELAMAT (FA12015) SUPERVISOR: DR.

(Lee Jeong, 2010) By dividing production planning and scheduling as two separate process, the time consumed for approval of plans for production had increased. The complex organizational structure in the firm takes about two weeks to approve the production plans, which is then passed down to the Material requirements planning system for scheduling. Occurrence of any errors leads to rescheduling of workers and component parts for assembly and cannotRead MoreCase Study : Medtech Eletronics Equipment Manufacturer Essay1413 Words à |à 6 Pagesstudy will discuss MPC and explain the 3 parts of MPC (Manufacturing Planning and Control) Framework which are front end, engine and back end. After that the essay will connect MPC and the 5 problems to find solutions which are production scheduling, engineering control, ISO 9000 or six sigma quality control systems, ICTs systems for communicating and just in time (JIT). Finally the writer will show the summary of this study. 2.

This machine has a direct consequence on the number of operation that is fixed and indirectly reflects on the total number of operation present in the potential re-scheduling. Instances of the job shop problem (10x10, 8x15, 5x10, 10x 15, 5x15, 5x20, 6x24, 10x20,) are considered. Two machines can influence the decision variables. Several cases with different values of this parameter are studied.

In order to increase the diversity of the population, a mixed selection operator based on the fitness value and the concentration value was given. To make full use of the characteristics of the problem itself, new crossover operator based on the machine and mutation operator based on the critical path were specifically designed. To find the critical path, a new algorithm to find the critical
