Design and application of model to improve productivity based on human factors;

Revision of the productivity and consuming rate of fuel of asphalt batch mixer under tableland circumstance;

Research on running performance and productivity of loading machines under tableland circumstances;

Under the assumptions that demand rate is price-dependent,production rate is controlled by demand and order cancellation rate is constant,a production-sale model is established for deteriorating items with advance sales and spot sales over the finite planning time.

Based on Differential, the control model of production and storage was set up with the production rates of workstations as its control vectors and the overall production rate as its objective function.

This paper deals with the new production-inventory model with the same limited time of free backorder for each clints,under the conditions of constant demand rate and finite production rate.

One problem of the traditional casting-rolling process is lower production efficiency.

By way of testing analyse cylindrical roller bearing ring turning outside diameter allowance influence on grinding processing and product accuracy,so as to re ducing turning outside diameter allowance,good at adjusting grinding process,reducing rejection rating and raising production efficiency.

From the point of economists who analyzed the relationship between technique development and economic increase, this thesis discussed the function of technique reform performing in economic increase concretely from three aspects ,such as technique reform and product increase、rate of production and advantages of enterprises competition.

In the paper,building up superior produce to plan the model,Main under the condition that rate of production be free from limit or rate of production have an up boundary limit,build up the model respectively,carry on discussion s combine end give .
