Abstract:
To study the problems caused by job assignment and sequencing in seafood export industry by focusing on 3 products; fresh shrimps, fresh fish and fresh squids, as well as on the production following the customers order which depends on manpower and then sent to stock in the warehouse waiting for delivery to the customers. According the present problems analysis, it is found that 22% of report from all process routes cannot be sent just in time and the expenses of hiring overtime workers to solve the problems of delayed work average around 200,000 baht per month. Moreover, it is found that workers are always transferred from one process route to another one, which shows that the present job assignment and sequencing cannot solve the problems presently occurred. According to the analysis and problems conclusion, the researcher has developed the computer program based on the principles of production planning, job assignment and sequencing. The major purpose is to solve the problem of delayed work, reduce the expenses of hiring unnecessary manpower and develop the program to increase the efficiency of data processing. When testing the developed program with the past productions information, no delayed work is found while with the existing program, there is 20% of delayed work. This shows that the developed program can aid job assignment and sequencing resulting in reduction in delayed work. Besides, with the developed program, the expenses of hiring overtime workers are reduced with 28% less than in the past, showing that there are unnecessary manpower hiring in the past. When testing the developed program with the present productions information in line with the job assignment and sequencing, the program can make the good results.
