Abstract: In this paper, an algorithm, known as the Max Plus Algebra (MPA)-algorithm is presented for analytical model building and performance evaluation of manufacturing systems. The manufacturing system is divided into three types of logical modules, namely, a serial production system, an Assembly System (AS) and a Disassembly System (DS). The three logical modules are modelled using place-Timed Event Graph (p-TEG). Max-plus equations are derived from the p-TEG model using the MPA-algorithm. An illustrative cyclic manufacturing system consisting of all three logical modules is taken to explain the modelling methodology. The flow time of the system is evaluated using Karp's theorem.
Keywords: max-plus algebra; p-TEG; place-timed event graph; flow time; Karp|s theorem; modular production systems; modelling; performance evaluation; manufacturing systems analysis; serial production; assembly; disassembly.
