چکیده

As advancing technology makes Flexible Manufacturing Systems (FMS's) a viable option for an increasing number of firms and products, determining their economic value has become increasingly important. Despite considerable research in this area, the effect of the ability or inability to hold interperiod inventories on the value of FMS's has received relatively little attention. This paper proposes a stochastic dynamic programming model for the production capacity investment decision that explicitly allows the firm to carry interperiod inventories for safety stock and seasonal stock motives, and it analyzes a simplified convex programming model that considers seasonal stock motives only. A variety of qualitative results are obtained for the case of periodic market conditions that are not known when the firm makes its investment decision. The complete solution is reported on for the case of deterministic periodically varying market conditions. Examples are given for both cases. The analysis leads to some surprising results, including the fact that interperiod inventories and flexible capacity can be complements as well as substitutes. Hence, the analysis can be an important supplement to unguided intuition. Seasonal Inventories and the Use of Product-Flexible Manufacturing Technology Jonathan P. Caulkins Charles H. Fine

Monte Carlo Simulation to Compare Markovian and Neural Network Models for Reliability Assessment in Multiple AGV Manufacturing System

We compare two approaches for a Markovian model in flexible manufacturing systems (FMSs) using Monte Carlo simulation. The model which is a development of Fazlollahtabar and Saidi-Mehrabad (2013), considers two features of automated flexible manufacturing systems equipped with automated guided vehicle (AGV) namely, the reliability of machines and the reliability of AGVs in a multiple AGV jobsho...
