To ensure the proper functioning of the repair and maintenance system, it is necessary to obtain and store data on the operations that are carried out. Managers of the enterprise can reduce the cost of repair and maintenance by using the graphics and reports that they can produce with the system with the help of the recorded data. Thanks to maintenance& repair systems, cost and duration of maintenance and downtime are reduced, performance of the personnel is improved and the expected lives of the assets are increased. At the end, enterprises have a stronger position in terms of their future in their respective sectors and increased profitability. In this work, feedback coming from the customer has been reviewed and evaluated to make the maintenance and repair system more complete and compatible with the operations of the companies and institutions. Software has been improved in accordance with feedback taken from the customer. New models have been added. Integrations have been completed; and electronic signature application has been included. Thus, the work has aimed at making the maintenance and repair system, which is designed in line with the needs of the companies, compatible with new developing technologies. New modules have been added by developing new features in accordance with the changing customer demands. With these newly added modules, a user-friendly maintenance & repair system has been designed. Moreover, thanks to the new system, solutions have been developed to problems, which could pose serious challenges to enterprises in repair maintenance, such as cost increases, erroneous planning of resource-work program and increase in downtime due to delays in approval flows.

Introduction While establishing a company, first, a physical unit is created. A plant is established and necessary equipment is purchased. To initiate the production, raw materials and means of production are channeled into the process. The marketing and sale of the product which is obtained as a result of these processes make the continuation of the (production) cycle possible, enabling the regular operation of the plant. In this situation, the company has to make planning of its resources and raw material in order to survive the competition and to grow. It has to closely follow resources and performance of the work force used in production and to keep these resources robust. Moreover, another very important factor in increasing the profitability of the company is keeping regular maintenance of the equipment bought and the plant established by the company in order to make production possible. At the end, the functioning of the plant’s production capacity is maintained and its useful life is extended. Behind the companies’ success in achieving efficiency and increase in profitability there are asset management systems. Personnel responsible for the maintenance of the assets have command of work steps and related maintenance plans, which are necessary to realize the maintenance of the assets. Nevertheless, when the enterprise gets bigger and asset lines are extended, even experienced maintenance personnel cannot keep up with the work load. This fact forces the company to employ new resources and personnel. As a result, additional costs are incurred. Moreover, transferring the knowledge of work steps and maintenance of instructions could create some problems. Asset management system is needed for documentation and management of these work steps and maintenance instructions Company managers want to have information on the kind of maintenance work carried out daily, monthly and annually; the costs; the situation of the personnel management; downtimes for the machines and the system; and working hours of the employees. The graphics related to such information could be produced by the maintenance and asset management systems.
