A Method Of Cost Management For Random Material-Flow Net In Steel-Rolling And Application

This dissertation is faced to the process of steel rolling to found network of manufacture material flow, basing on it founding guide line evaluation system of the cost of unit standard producing working procedure, guide line evaluation system of the quality cost of unit standard producing working procedure and guide line evaluation system of performance and efficiency; and base on the cost data of all kinds of material flows, manufacture flow, flux data, manpower, energy consume, material consume, capital asserts occupied, fund occupied, and the production in working procedure, throughput of the materials in working procedures in the flow and countercurrent flow in the network of material flow of recorded in working procedure producing, using the"whole closed down lane"model to describe network of manufacture material flow of steel rolling, found the cost analyzing model system of the network faced to producing process. Make the cost increasing of the producing by abnormity material flow in working procedure,and even the cost increasing of the producing procedure as the cost of the management behavior of working procedure fallen under cost evaluation guideline in responsible working procedure, so as to ration measure the factors fast correlated with management behavior by measuring the cost. For the correspond and the matching of normal material flows between working procedures in the flow, we will base on the supply process of previous working procedure and the incept process of working procedure to define the process ability index of the two processes, and this index integrated reflect the assembly ability of the working procedure and the organizing and management ability in the production.Base on single evaluation system of performance and efficiency in the working procedure, we found multi-index integrated evaluation model- C2 R model and C 2GS2model which based on DEA (Data Envelopment Analysis) basic model, and show different rules of multi-index integrated. Finally, we will do some demonstration research in cost and quality cost evaluation system in then material flow which we founded.The content of this dissertation:Founding the network topology-chart in main production flow of the...
