| Abstract | Just-In-Time (JIT) and Material Requirement Planning (MRP) are the major approaches in
controlling production system. Each has its own advantages and disadvantages. Mix pull/push
strategy is the one that try to inherit the benefits of both pure pull and pure push production
systems. CONWIP system was regarded as a hybrid pull/push production system, that can
achieve the same throughput rate with a lower WIP level comparing to Push system.
A mathematical programming model was built to integrate scheduling and sequencing for
CONWIP, Push and Pull systems. This model determines the efficient products' sequence and
production schedule that gives the minimum total cost (processing cost, set-up cost, and
holding cost). In doing so, the model also gives us estimated stait and finish times of each pa1t
in the system.
The problem is a Non-linear Mixed Integer Mathematical Programming. It consume a huge
amount of time to solve for optimization, in some case it can not solve because of the large
size. Tahu Search is used to solve heuristically that can reduce a lot of calculation time.
Computational testing shows that the heuristics gives fairly good solution. |
