Methods and tools for optimal planning of process parameters in aftersale service systems of high technology products

The methods and software tools of aftersale systems optimization are considered based on cost criteria for a given level of technical operability coefficient are considered. A brief overview of current approaches to product lifecycle management of high technology products, based on the Western concept of CALS (Continuous Acquisition and Life cycle Support) and its Russian analogue — IAS (integrated information support of products) is provided. A new stochastic approach to modeling of aftersale systems for products of high technology is presented. This approach is used to solve the actual problem of optimal design and operation of service system based on cost criteria. The methods for finding optimal values of service systems using different measures of efficiency are described. Methodological and instrumental software tools for cost optimization of spare parts supply and repairs for years to come, until the write-off of the device under restrictions on allocated financial resources and the need to maintain a given level of technical operability coefficient, are demonstrated.
