Abstract
It is challenging for maintenance of activities to be assured during products’ life cycle when poor maintenance is the case. Poor maintenance of engineered products will lead to an increment in cost and time is fundamental in the development of maintainability tasks for engineering firms. Maintenance design had played a significant role in complex designing of engineering products. This research presents a critical approach to evaluate and determine a maintainability index using the assembly principle. Normally, time is a critical indicator and parameter being utilized to measure maintenance; however, minimal efforts have been focused on assembly components and the principle of assembly. In the past literature works, customer study and survey on the effects of operators’ skills have been done. In this research, maintainability index is determined. Every assembly type is weighted with reference to features such as assembly direction, costs and disassemblability. Resultantly, this research seeks to enhance the efficiency of maintenance of engineered products.

Summary
The function of maintenance determines rate of completion of a specific maintenance task of engineered products. Contextual principle incorporate redundancy for elements presented in multiple occurrences such as competency, which represents human need to repair or diagnose. Another aspect is tooling, maintenance tools and equipment e.g. screwdrivers, keys etc.; Logistics, spare part delivery, transportation of maintenance group; Environment, operating situations such as temperatures or lighting; fault identification, testability, delectability of components to be evaluated. The feature of maintenance is applied in the description of maintenance design and essential data [5] It incorporates maintenance organization element, maintenance resource, maintenance feature, maintenance process, using demand, fault feature, maintenance program, maintenance quantitative and qualitative demands, maintenance design evaluation results, and personnel model information among others.
