Calculation methods for mean waiting time of maintenance support

In order to analyze and evaluate the timeliness of the support system during the design and development phase, the concept of waiting time of maintenance support (WTMS) was discussed. The impact factors of WTMS during the design process of the support system for the equipment was analyzed, including the frequency and location of the support activities, depth of maintenance of the support sites with different lines of maintenance, distribution of the support sites and allocation of the support resources in them, transportation means between different support sites and other factors.A calculation method for the mean waiting time of maintenance support was established based on statistics and matrix theory, which used the results of supportability analysis as input and considered the difference in calculation methods between the consuming support resources and occupying support resources. A case of the calculation method was provided to verify its feasibility and correctness.
