Nowadays, sustainable development has increasingly drawing public attention due to environmental, economic and social reasons. To pursue a more competitive and sustainable society needs greater concentration on waste management. However, waste management is a worldwide challenge, because several interactive influencing factors, i.e., costs, risks, equity, etc., and the characteristics of different regions have to be simultaneously taken into consideration. The optimal solution for one influencing factor is usually not a good choice for another. Therefore, it is highly preferred to develop a sophisticated system analysing tool for managing those interactive influencing factors as well as the characteristics of different waste management systems in an efficient and sustainable manner. In this paper, a decision aided system based upon multi-objective programming is proposed for addressing the optimal trade-off among costs, risks and sustainability of waste management system from long-term perspective. A theoretical framework of sustainable waste management is first established, and the mathematical model as well as the computation method is then formulated accordingly. To present the application of this model, an illustrative calculation is performed as well, and the model computation in this paper is done by using programming language in a professional optimization software Lingo 13.0.

This paper examines differences in bank efficiency between banks affiliated with single-bank holding companies and those affiliated with multi-bank holding companies by applying a fuzzy multi-objective two-stage data envelopment analysis technique. Using a sample of U.S. commercial banks covering 1994-2018, the results show that banks affiliated with multi-bank holding companies are more efficient than those affiliated with single-bank holding companies, suggesting that the former takes advantage of their parents' resources to enhance their efficiency, consistent with the internal capital market theory. They also show that banks with a powerful CEO exhibit lower efficiency than others. Moreover, there is an inverted U shape relationship between multi-bank holding company structure and bank efficiency, suggesting the presence of an optimal number of multi-bank holding subsidiaries that maximizes efficiency.

San Antonio Bay is located on the coast of Texas between Galveston Bay and Corpus Christi Bay and is the primary bay in the Guadalupe Estuary. Three rivers feed San Antonio Bay from two river basins, including the Blanco and Guadalupe Rivers in the Guadalupe River Basin and the San Antonio River in the San Antonio River Basin. The Canyon Reservoir regulates the flow of fresh water in the middle and lower reaches of the Guadalupe River These inflows are a primary regulator of salinity and, thus,,the productivity of commercially important estuarine species. Increasing demand for water has prompted plans for an increased diversion of 49.3 million m(3) (40, 000 acre-feet) from the reservoir An additional amount of 61.6 million m(3) (50,000 acre-feet) from the mouth of the river is to be pumped back to, San Antonio to relieve over-pumping of the Edwards Aquifer. Because the Guadalupe River Basin contributes 58.1 percent of the freshwater inflow to the estuary, it is not known what the impact of these actions will have on the ecological integrity of the San Antonio Bay. Water resource management in the San Antonio Basin consists of decision making under risk and uncertainty related to randomness in the critical parameters such as the salinity in the bay, biological productivity, and total flow into the bay. The aim of this study is to investigate the trade-offs between the competing objectives of maximizing biological,productivity in the bay and minimizing flow using Stochastic Compromise programming (SCP). The SCP model solves a multi-objective function subject to constraints that must be maintained at three different Prescribed levels of probability providing a global set of solutions for the water resource management problem under input uncertainty. The SCP model provides information on the trade-offs among the objective function value, tolerance values of the constraint at the prescribed levels of probability, which could be valuable to policy makers in risk assessmen

Regarding a two-echelon supply chain consisting of a logistics service integrator (LSI) and several functional logistics service providers (FLSPs), this paper establishes a two-stage order allocation model considering demand updating and the FLSPs' fairness preferences. This model is a multi-objective programming model, whose goal is to maximize profits of the LSI and the total utility of FLSPs. The ideal point method is used to obtain the optimal solution. In the numerical example, the impacts of FLSPs' behavioral parameters and demand update parameters on the order allocation in the social services network are discussed. Besides, multi-methodological method is used to verify the theoretical perspectives through an empirical study of Tianjin SND Logistics Company. Our study obtains a few important conclusions. For example, when demand of the second stage is updated, there is an optimal updating time maximizing the supply chain performance. Increased demand of the second stage results in greater supply chain performance. When the demand during the second stage decreases, the bigger the difference of the fairness preference coefficients among FLSPs, the greater the LSI's profits and the lower the FLSPs' total utility will be. However, the difference of the fairness preference coefficients among FLSPs has little influence on the LSI's profits and total utility of the FLSPs, when the demand during the second stage increases.

The semi-arid loess hilly-gully region in China has an extremely vulnerable ecological environment. Inappropriate land use - crop farming, overgrazing, and plantation forestry - has worsened soil erosion, intensified water shortage, and hence impeded the ecological conservation and agricultural development of the entire region in the past. Optimizing land use and vegetation cover and spatial pattern is conducive to achieving both ecological and economic goals in terms of controlling soil erosion, using water resources rationally and raising agricultural productivity. Changchuan Watershed, a typical small catchment in the semi-arid loess hilly region, was selected as the case study area to analyze the impacts of land use and land cover structure and associated spatial pattern on soil erosion and water consumption in the Watershed, through field investigation and model simulation. Land use structure was optimized by multi-objective programming, using remote sensing (RS) and geographical information system (GIS) techniques, analytic hierarchical programming (AHP) and expert consultancy. The digitized optimum spatial pattern embodying rationally-proportioned land use structure was obtained through GIS-aided redistribution of land use types. The optimized land use structure reapportioned woodlands, shrublands, grasslands, and croplands at 3.7%, 38.6%, 49.4%, and 6.3% of the land area respectively, compared to the current land use structure of 2.4%, 38.6%, 24.0%. and 12.6%, respectively, in the Changchuan Watershed. In the optimized land use spatial pattern, croplands are mainly located in the riverside plain and check-dammed valleys and grasslands are widely distributed in the lower reaches of the basin, while shrublands are appropriately established in the middle and upper reaches of the river. A comparative analysis shows that the optimized land use structure, with well-designed spatial pattern is able to reduce soil erosion, enhance the utilization of water resources

Modelling the trade-offs between farm income and the reduction of erosion and nitrate pollution

Water is a very limited resource in Tunisia, both in quantity and in quality. Problems of quality are related to urban, industrial and agricultural activity. Erosion is causing dams to silt up and is leading to phosphorus accumulation in water. The use of agrochemicals, primarily nitrogen and phosphorus, is causing problems of eutrophication. This paper presents the results of a study of sediment and nitrate pollution. The methodology used is based on the EPIC simulation model and a multi-objective programming model (MOPM). The data generated by EPIC are input for the MOPM together with the economic variables. These tools are applied to a 486 ha farm located in northern Tunisia which includes an irrigated area of 300 ha. The study considers three objectives: maximization of gross margin, minimization of erosion, and minimization of nitrate losses. The non-inferior set estimation method is implemented to generate the trade-off curves between the objectives. Results show that nitrate losses are important for both rainfed and irrigated land. The same conclusion is valid for erosion. It is shown that the farmer can reduce the environmental burden without decreasing gross margin, since he is operating below the efficiency curve.

AGRICULTURAL SYSTEMS 2014年 130卷 116-125页

Agricultural land use allocation involves assessment of land potential as well as land demand for various crops to identify the optimum land unit for each type. Current allocation models often focus on the perspective of increase in land demand. However, processes causing loss of arable land should be considered to correct the demand used in conventional allocation processes. In order to achieve that, a two stage model for crop allocation is presented which uses different models such as cellular automata, Markov chain, fuzzy rule-based system, goal programming and GIS raster analysis in a logical framework. In the presented model, at first by considering environmental (soil erosion and soil salinity) and economic (urban expansion) factors leading to arable land loss, agricultural use of each land unit is allocated. Next, crop types within the agricultural area are determined based on land suitability evaluation and demand assessment for each crop. This model is developed for rural land use planning on a regional scale and is applied to the Borkhar and Meymeh district in Isfahan province in Iran to predict land use map of 2015. The overall accuracy of 0.609 in the first step allowed us to draw conclusion that the inclusion of factors resulting farmland decline in allocation process gives more accurate results than the former allocation techniques which merely model factors causing increase in agricultural land areas. Moreover, according to the results for 2015, 27.82%, 21.64%, 7.27%, 5.85%, 7.36%, 6.36% and 1.74% of agricultural areas is allocated to wheat, wheat-maize, barley, barley-maize, maize, alfalfa and potato, respectively. The presented approach has advantageous to determine the crops with highest suitability for a given area according to the desired objectives. (C) 2014 Elsevier Ltd. All rights reserved.

This paper suggests an efficient procedure to search for efficient/satisfactory solution of multi-objective Fully Quadratic Fractional Optimization Model with fuzzy coefficients using alpha-level set and FGP approach. Quadratic fractional objectives are hard to handle due to their complex structure and need to be converted into non-fractional form. Till now, Taylor's series or parametric method is used to employ simpler objectives. But their always exist chance of error due to truncation of infinite series. Here, a new method is induced to have non-fractional fuzzy goals and in the final step, the linear weighted sum of negative deviational variables is minimized to satisfy all objective functions upto maximum possible extent. In the end, an algorithm, flowchart and numerical are also given to clarify the applicability of the suggested approach.

With the trend of high proportion of renewable energy connecting with grid, peaking services has played a crucial role in the integration of wind power and other renewable energy sources. The current peaking service takes into account only the cost of thermal power units that providing peaking service without considering the impact of its own reliability on the peaking service and the safe operation of the power system. In this paper, the traditional uniform clearing mechanism has been improved, and the reliability factor of ancillary service provided by thermal power units has been included in the previous quotation-based sorting rule, and a multi-objective programming optimal purchasing model considering synergistic capacity cost and power system stability is established. According to the optimal solution of each objective, Pareto optimal solution of multi-objective programming problem is obtained by the ideal point method. Then the ancillary service price and purchase cost are obtained based on the solution.
