    Shop floor control systems supporting teams

    The increasing number of companies that change their shop floor organisation towards group and team work causes the need for new technical aids that are suitable for groups. Until today the cooperation and coordination of teams was supported by software only on office level by so called groupware. The short term scheduling seems to be a promissing field of application for improved forms of decission support on shop floor level in order to increase productivity. Latest research about the tack knowledge of workers for the task of shop floor control shows, that all members of a production team have their individual implicit knowledge. These pieces of knowledge have to be combined in order to optimise the production. A decision room with a new scheduling system is suggested to fulfill the demands mentioned above.

    Group work on shop floor level gains an increasing importance, because it enables better usage of capacities, mutual help in difficult situations and mutual learning support. Higher customer orientation causes more unpredicted situations that increasingly demand decentralized short term decision making. Principles of wholistic tasks, of flat hierarchies with distributed responsibilities and latest research about gaining and use of experience at shop floor level form an approach of cooperative an coordinated decision making. The task of scheduling is seen as a task that requires much joint decision making within a group, as well as a high degree of coordination with remote departments. The proposed approach postulates enhanced functionality of shop floor control software (SFC), hardware that enables joint decision making (whiteboard architecture) for groups and interacting networking software that allows to use company wide data and software applications of other departments.

    Computer supported experience guided work -CeA-

    An increasing number of computer systems, e.g. shop floor control systems are introduced on shop floor level. factories with manual driven systems have most of their planning activities handled by experienced craftsmen and skilled workers. Implementing computer-based shop floor control systems in such structures means, that people have to change their way of thinking, because there is no way to put their experiences into the systems or use it in the former way. The handling of the systems occupies them more than the task of problem solving itself. The effect of introducing the computer system is therefore less than expected. Within the project CeA, an interdisciplinary team is looking for circumstances how ecperience is aquired and used. In the empirical phase of the project we found, that many tasks like judgement about the momentary capability of a skilled worker to give him the right job are made informally by using experience and can not be solved by a computer equally. The second question is how to support the experience of craftsmen and skilled worker sand their decision making by computer systems. The aim is to develop a new generation of computer systems for the shop floor with some features as broad data access, simulation and graphical animation and fedback about the results of the decisions.
