To solve the basic man-hour data scarcity and avoid difficulties in establishing it, an assembly task man-hour estimate model based on work study and primitives is presented. Since the assembly tasks consist of manual operations mainly, methods study is used to get standard task firstly, then the manual standard tasks are disassembled into simple and(More)
In order to realization electronic parts product appearance quality detection control, one kind of processor based on the intelligent knowledge automatic extraction and system intelligence modeling was presented. In the processor, wavelet-fuzzy technique and neural network technique are combined. Uses the fuzzy wavelet extraction image feature, and wavelet(More)
To solve the problems that basic man-hour data scarcity and avoid the difficulties in delivery deadline establishment and information communication, the research on man-hour calculation and cooperative management system of multi-stage manufacturing system was presented. The system consists of three modules. Aiming at a three-stage manufacturing system(More)
Mixed model assembly lines are attractive means of mass and large-scale series production. Determination of the production sequence for different models is a key issue in the mixed model assembly line. Particle swarm optimization (PSO) is a novel metaheuristic inspired by the flocking behaviour of birds which has be used in consecutive problems(More)
In order to realization electronic parts low-voltage wire winding techniques product appearance quality detection control, one kind of coordination intelligence information processor(CIIP) based on the knowledge automatic extraction and collaborative manufacturing system integration modeling was presented. In the processor, utilization of wavelet-fuzzy(More)
Pressed by the fierce competition in the auto electronic parts market, we have explored a new production management approach based on manufacture execution system (MES) out of actual needs of the auto electronic parts enterprises to meet the rapidly changing market demands. Technically supported by Web service, XML technology, B/S structure and Microsoft(More)
