Article Abstract:
Technological flexibility requires very high initial investments and therefore a decision to acquire it is both risky and strategic in nature. The objective of this paper is to find out the technological flexibility requirements in just-in-time manufacturing under different environmental situations. The simulation results show that the incorporation of flexibility in a manufacturing system is vital. The choice of the extent of flexibility is driven by the market and economic factors.

Article Abstract:
An interval programming model was utilized to illustrate post-design decisions in a cellular manufacturing system. The model, which involves objective function coeficients that are expressed in range instead of a point estimate, takes into consideration informational uncertainty related to exceptional elements and bottleneck machines' cost estimates. It also involves lessening of interval objective function by transforming it into a multi-objective problem utilizing order relations.

Article Abstract:
A model utilizing a three-stage sequential procedure worked effectively in the development of production planning and scheduling for injection moulding of pipe fittings. The model was shown to formulate a production planning and scheduling that greatly lessen the overall costs associated with injection moulding of PVC pipe fittings in a factory. The model was able to use forecast data in a formalized manner and finalize plan in a shorter time.
