The Man-machine Integration Design and Analysis System (MIDAS) is an integrated human performance modeling software tool that is based on mechanisms that underlie and cause human behavior. A PC-Windows version of MIDAS has been created that integrates the anthropometric character "Jack™" 1 with MIDAS' validated perceptual and attention mechanisms. MIDAS now models multiple simulated humans engaging in goalrelated behaviors. New capabilities include the ability to predict situations in which errors and/or performance decrements are likely due to a variety of factors including concurrent workload and performance influencing factors (PIFs). This paper describes a new model that predicts the effects of microgravity on a mission specialist's performance, and its first application to simulating the task of conducting a Life Sciences experiment in space according to a sequential or parallel schedule of performance.

Discusses briefly the impact of MRP on UK manufacturing industry in the context of the next generation of developments. Draws a contrast with production planning and control systems in Germany which derive shopfloor control through different architecture of business control systems. Presents the state of these developments in Germany as analysed by a leading academic institution (the FIR at Aachen University of Technology). Compares this with UK developments, as seen by the Liverpool short‐term scheduling group, which recently has analysed production planning/ scheduling practice in a range of different companies across various industry types. Offers the view that future PPC systems will be based around simple “core logic” with tailored subsystems, possibly built by manufacturing companies themselves.
