Object oriented programming in production management—two pilot systems

Abstract

This paper discusses AI-oriented production management systems using object oriented programming. The two pilot systems described here are both implemented using the Smalltalk-80 programming environment. One of the systems concerns production planning in dairy industries, while the other is a simulation tool for production flow analysis. The merits of object oriented programming in the design of the user interfaces are emphasised. The flexibility of the object oriented approach for stepwise development has been observed. Simulation method as a communication tool is used in both systems and the applicability of Smalltalk in simulation is demonstrated. Design effectiveness and efficiency has proven surprisingly good. The experiences introduced in the paper are based on two geographically disjoint research groups, having thus impact on the generality of the observations made.
