The interest of firms in ERP systems has been echoed in both the scientific and professional literature. It is worth noting however that while this literature has become increasingly abundant, there does not yet exist an operational definition of the ERP concept that is, if not unanimously, at least widely accepted. This constitutes a handicap for both the research and practice communities. The...

This paper proposes optimal operational planning for cogeneration system (CGS) using particle swarm optimization (PSO). CGS is usually connected to various facilities such as refrigerators, reservoirs, and cooling towers. In order to generate optimal operational planning for CGS, startup/shutdown status and/or input/output values of the facilities for each control interval should be determined....

We describe and solve a real world problem in chemical industry which combines operational planning with strategic aspects. In our simultaneous strategic & operational planning (SSDOP) approach we develop a model based on mixed-integer linear (MILP) optimization and apply it to a real-world problem; the approach seems to be applicable in many other situations provided that people in production ...

Concurrent strategies are shown to support operations yielding an economic yet rich higher-order concurrent process language, which shares features both with process calculi and nondeterministic dataflow. Its operational semantics and ‘may and must’ equivalence require that we take internal (neutral) moves seriously, leading to the introduction of ‘partial strategies’ which may contain neutral ...

We present an environment for web-based simulation of influence nets to be used for operational planning. Previous work in this field has shown how influence nets, which are used for probabilistic modelling, can be extended with time and then translated into a coloured Petri net to do temporal evaluation of plans. Simulating the coloured Petri net model in a web environment makes it easy for a ...

This paper describes HICAP (Hierarchical Interactive Case-based Architecture for Planning), a general purpose planning architecture that we have developed and applied to assist military commanders and their staa with planning NEOs (Noncom-batant Evacuation Operations). HICAP integrates a hierarchical task editor, HTE, with a conversational case-based planning tool, NaCoDAE/HTN. In this applicat...
