Abstarct: Long-term load management is the process of optimal use of resources baxsed on management principles in order to provide reliable and stable electricity over a long period of time. This requires long-term asset management and the optimal use of resources and proper timing in the creation, maintenance, scrapping and disposal of facilities and evaluation of efficiency and productivity over a lifetime. Due to the natural monopoly on electricity distribution infrastructure, many countries have moved to transfer ownership or management of electricity distribution infrastructure to the private sector. The companies will be separated into wired companies to maintain and upgrade the electricity distribution infrastructure to consumers and retail companies to buy large energy packages and sell them in retail. Was to subscribers. By delegating the process of electricity distribution to the non-governmental sector, creating a competitive environment to improve the quality and rate of services has become particularly important. Due to the multiplicity and variety of influential variables in distribution companies, a comprehensive model has not been defined in this regard, so due to the lack of model and the impossibility of simulating and evaluating system behavior in the event of new policies, distribution regulation in a process Gradually in the form of trial and error and using the experience and expertise of the responsible factors in this field. In order to achieve a basic model for long-term studies, in addition to the need to identify the factors and variables inherent in the system, identifying other factors and variables that lead to the imposition of costs is of great importance. One of the most basic approaches to effective regulation in distribution companies is to separate these factors into internal and external factors. Urban planning, social behavior, and governance are important and influential external factors on asset and burden management in distribution companies. In this dissertation, the efficiency evaluation of different regions of the North Kerman Electricity Distribution Company in the field of street lighting has been studied as a study sample and regulatory mechanisms to improve its efficiency. In order to achieve the intrinsic variables of the street lighting system, the technical characteristics of the facilities have been used and using them, the basic model has been calculated to evaluate the areas. In the simulation, the difference between the model output statistics and the actual statistics is attributed to the influence of external factors. Then, by defining an incentive mechanism for encouraging and punishing electricity contractors and managers in the regions, they are given the opportunity to minimize the impact of external factors. The results show that these mechanisms ultimately lead to encouraging companies to enter into a contract to purchase lamps with an unconditional warranty for the average life and deviation from the average life, as well as encouraging executives to identify the defect and fix it in the shortest possible time. Finally, it is proposed to increase the time period of contracts, considering the life of street lighting facilities, so that contractors can benefit from distribution companies by increasing long-term planning while earning more profit.
