<p>Pulau Morotai Regency is one of the areas identified by the government as a fisheries-focused Special Economic Zone. However, the reality on the ground is that the fishing industry has only one cold storage facility. One of the factors is the region's remote position, which requires a considerable amount of capital and operational expenditure. Lower energy costs are one way to reduce the operating cost. This study aims to determine the value of each energy-efficient criterion and to know the most efficient energy composition implemented for Cold Storage in Morotai. This study uses the decision matrix approach to compare the operating costs of cold storage with a capacity of 200 tons over 20 years with three possible alternatives: PLN electricity, hybrid electricity (PLN + photovoltaic), and fully photovoltaic energy. With a score of 38 in the decision matrix table, the outcome of the decision matrix calculation indicates that cold storage with a photovoltaic system is much superior.</p>

Though Performance of a city depends on the quality of transportation system performance,including the performance of public passengers transportation. This study aimed to produce aconstructive information to support the APU vehicles renewal in public passenger transport operationMalang better. This study has an empirical method, refers to the decision of Director General ofLand Transportation No.687/AJ.206/DRJD/2002 and the Minister of Transportation Decree No.89/2002. The results of the study showed that the average of the vehicle operating costs (renewalvehicles) is Rp. 121,906,736, -/year or Rp. 1.671, -/km. Based on the average of the number ofpassengers (actual), it is shown that the difference of the average between acceptance of the tariffand the vehicle operating cost is Rp. 143,121.79 per-vehicle per-day.Keyword: public passenger transport, vehicle operating cost

Efficient Distribution

An efficient distribution center (DC) is one that receives, stores, picks and packs products into new logistics units and then dispatches them to points of sale at the minimal operating cost. The picking and packing processes represent the highest operating cost of a DC, and both require a suitable space for their operation. An effective coordination between these zones prevents bottlenecks and has a direct impact on the DC’s operational results. In the existing literature, there are no studies that optimize the distribution of the picking and packing areas simultaneously while also reducing operating costs. This article proposes an integer nonlinear integer programming model that minimizes order preparation costs. It does so by predicting customer demand based on historical data and defining the ideal area for picking and packing activities. The model is validated through a real case study of seven clients and fifteen products. It achieves a [Formula: see text] reduction in operating costs when the optimal allocation of the picking and packing areas is made.

Abstract In 2018, the Government of India approved the establishment of the New All India Institute of Medical Sciences (AIIMS) in Thoppur, Madurai, Tamil Nadu, India. As the most important amenity for continuing primary care and rescue response is a healthcare facility, a secure electricity supply becomes an imperative necessity. Hence, as the energy supplier for the new AIIMS, Madurai, this paper proposes a microgrid combined with the utility grid. The microgrid consists of a 4-MW photovoltaic system, a 1.8-MW wind-turbine energy-conversion system, a backup diesel generator capable of meeting the forecasted maximum demand and a 1-MW battery energy-storage system. The AIIMS Microgrid will have a service providing a capacity of 20 MVA following integration with the utility grid. The proposed microgrid would be the first attempt at healthcare facilities in India since its first day of work to ensure the availability of electricity. It would have a 9.8% return on investment, a 13.6% internal rate of return and a payback period of 6.75 years once it is operational, as well as an attractive levelized cost of energy (LCOE) of USD 0.07547/kWh. It would provide an environmentally friendly atmosphere by avoiding an annual emission of 6 261 132 kg of carbon dioxide, 27 362 kg of sulphur dioxide and 12 838 kg of nitrogen oxides as compared to power supplied entirely from the utility grid.

The federal government withdrew from the field of direct financial support of universities in 1967 under provisions of the new Act. Along with the full responsibility for university finance, the federal government transferred to each province certain tax revenues and a post-secondary education adjustment payment to bring the total financial transfer to at least 50 per cent of the allowable operating cost of post-secondary education. Costs allowable under the Act exclude capital costs, federal grants, student aid, and income for assisted, sponsored, and contract research. The federal councils and agencies continue to be the primary contributors to university research funds. The purpose of this note is to determine the current financial contribution of the government of Canada to university research. Much of the problem is its definition. To establish the framework for this definition, three sets of ideas are explored. These are: direct and indirect costs of university research, university research as an embedded activity, and the problem of relating university activity costs to incomes received from specific sources. These notions lead to formulae which yield divergent alternatives of the federal contribution depending upon the set of assumptions deemed appropriate. Much of the data needed for these calculations were gathered from primary sources and illustrate the application of the formulae for the four-year period 1966–70.

Real Option Method

Developing the waterway infrastructure construction can improve the efficiency of energy utilization, reduce the energy consumption intensity and carbon dioxide emissions. Till the year 2020, China plan to complete 19,000 kilometers high grade channel. Construction of water infrastructure construction requires a large capital investment. However, the main financial source of funding the construction of transportation infrastructure at present in China is special financial allocation of the government. The unitary financing structure as well as the funding pressure has leaded to some serious financing problems. This paper applied the real options theory to the waterway infrastructure construction financing, analyzed the limitations of the NPV method and the advantages of real option method in investment decision of waterway infrastructure construction, and took an example to show its feasibility.
