Credit allocation through the usage of Portfolio optimization mainly seeks tomaximize return and minimize the risk of the portfolio; but there are other importantissues including sustainable development which is important for government/publicsectors. This paper presents a novel credit allocation approach based on portfoliooptimization and investigates the effects of selected indicators of sust...

due to increasing demand for the scarce available water throughout the world it is an extremely important matter, in water management, to make serious attempts in determining its true economic value. this paper discusses the optimal allocation of water to agriculture, the relatively true economic value of water as well as the cropping patterns for the shirvan barzo (sb) dam area in north kh...

Truck-Shovel fleet, as the most common transportation system in open-pit mines, has a significant part of mining costs, for which optimal management can lead to substantial cost reductions. Among the available dispatch mathematical models, the multi-stage approach is well suited for allocating trucks to respected shovels in a dynamic dispatching program. However, with this kind of modeling sequ...

performance budgeting has been an important theme of public expenditure management for decades. in the 1990s, however, a new wave of enthusiasm for performance budgeting began to sweep through governments. in recent years, however, the level of interest in organizational use of performance-based budgeting re-emerged with more details and support from researchers and practitioners. performance-b...

The allocation of risks among the contracting parties in a contract is an important decision affecting the project success. Some risks in a project are uncontrollable; these are imposed to a project by external factors. Since contracting parties can neither control nor affect the occurrence of such risks, their allocation to a party would be inequitable. Therefore the cost overrun related to un...

In this paper, the common centralized DEA models are extended to the bi-level centralized resource allocation (CRA) models based on revenue efficiency. Based on the Karush–Kuhn–Tucker (KKT) conditions, the bi-level CRA model is reduced to a one-level mathematical program subject to complementarity constraints (MPCC). A recurrent neural network is developed for solving this one-level mathematica...

The supplier selection and order allocation are two key strategic decisions in purchasing problem. The review presented in this paper focuses on the supplier selection problems (SSP) and order allocation from year 2000 to 2017 in which a new structure and classification of the existing research streams and the different MCDM methods and mathematical models used for SSP will be presented. The re...

water quality aspect with regard to dissolved oxygen was studied for a 24 kilometer stretch of malaprabha river in karnataka state, india. main objective of the research was to simulate the predicted dissolved oxygen depletion due to the waste load allocation in the river with the ambient observed values of dissolved oxygen, and to ascertain the application of mathematical modeling for predicti...

One of the most important issues in area of health and hygiene is location-allocation of organ harvesting centers and transplant centers according to coordination between supply and demand. In this paper, a mathematical model is presented for location-allocation of organ harvesting centers and transplant centers. The proposed model does not only minimize the present value of the total system co...

The importance of innovation for sustained competiveness is well stated in the literature. However, most product innovation research has so far focused on large firms or small high tech, start-up or spin-off companies. This study investigates innovation process practices in small established firms through the use of five managerial levers considered to determine the process. Based on a case-stu...
