Abstract
The needs of the consumers about the functionality of a product and increase maintenance costs of equipment caused the prices of products and treatments to be expensive. Therefore, the company considers the lease rather than buy it. Leasing provides interesting strategy when dealing with expensive equipment. Policy maintenance that is done to the product that has decreased performance. Minimum repair done to fix failed equipment in order to return to operational condition, while imperfect preventive maintenance to improve the operational conditions of the equipment to avoid failure. Time duration for a minimum repair neglected. The lessor will charge a penalty (penalty cost) if the lease equipment failure. Mathematical model built for the minimization cost of maintenance policy. In the final part, the numerical experiment are given to show the maintenance policy taking into account the rate of usage (usage rate) by knowing the minimization the resulting costs.
Highlights
Some of the conditions encountered at this time where the consumer needs will be a function of products with increasingly diverse, more expensive production equipment, as well as the existence of a rise in the cost of production, equipment maintenance activities be the cause manufacturers are starting to think that being uneconomical again if buy equipment production
Attractive leasing options mainly deals with complex equipment in the form of expensive production equipment, medical tools, means of transportation, and others [2]
Research [5], investigated the limit value threshold of failure rates for products rent with Weibull distribution in lifetime and get the value of the threshold and optimum maintenance policy during the period of the lease
Summary
Some of the conditions encountered at this time where the consumer needs will be a function of products with increasingly diverse (multifunction), more expensive production equipment, as well as the existence of a rise in the cost of production, equipment maintenance activities be the cause manufacturers are starting to think that being uneconomical again if buy equipment production. Research [5], investigated the limit value threshold of failure rates for products rent with Weibull distribution in lifetime and get the value of the threshold and optimum maintenance policy during the period of the lease. Research [7], researching on granting a warranty on equipment if failure based on the concept of two-dimensional, where the repair tools in use is minimal and imperfect repair for find the total cost of the guarantee minimum expectations. Research [10], researching on optimisation strategy to repair the product based on the concept of two-dimensional warranty. In his research investigations about the strategy of imperfect PM periodically on a product with a combination at the time base warranty and extended warranty from the perspective of the company. Time PM and repair in minimal time, and ignore any failure will be given a cost penalty
