Discourse about Linear Programming and Lean Manufacturing: Two Different Approaches with a Similar, Converging Rational  [PDF]
Bruno G. Rüttimann
Journal of Service Science and Management (JSSM) , 2015, DOI: 10.4236/jssm.2015.81010
Abstract: In recent years, the Toyota Production System has also assumed in western manufacturing plants a predominant position. Lean Manufacturing, as it is usually called in the occidental world, aims at a “Single-piece-flow” job handling and has its advantages compared to the classic “Batch and Queue” job handling. On the other hand, mathematical Linear Programming optimization techniques have passed into oblivion, having obtained the feel to be inappropriate for production planning. Although the two approaches have different aims and application, they give particular attention to scarce resources. The concepts of “bottleneck” in Lean Manufacturing and “shadow price” in Linear Programming are complementary. The paper shows the different focus of the two approaches and crystallizes their synergic values.
An Estimate of the Shadow Price of Water in the Southern Ogallala Aquifer  [PDF]

Abstract: In this paper, we attempt to quantify the shadow price of an additional inch of groundwater resource left in situ for the Southern Ogallala Aquifer. Previous authors have shown the degree to which the optimal resource extraction path may diverge from the competitive extraction path based upon varying assumptions. We utilize high-quality data over an unconfined groundwater resource to evaluate the validity of these results. We find that the size of the existing groundwater resource is sufficiently small to result in a divergence between the competitive and socially optimal solutions. We are also able to confirm that the model responds to changes in the parameters in a manner consistent with previous research. Finally, we arrive at a marginal user cost for an additional acre-inch of water which is relatively low, but reasonable given uncertainty about future technological improvements.
Green Inefficiency for Regions in China  [PDF]

Journal of Environmental Protection (JEP) , 2010, DOI: 10.4236/jep.2010.13039
Abstract: We used the directional output distance function to derive estimates of green inefficiency, shadow prices, and waste costs of three wastes (waste water, waste gas, and solid waste) for thirty regions in China during the 1996-2003 periods. There is an upward trend in green inefficiency in Chinese regions from 1996 to 2003. The green inefficiency score in west area is the lowest but in central and east areas are higher. The costs of wastes have an upward trend in east and central areas but downward trend in west area in the last two observation years.

Abstract: Efficiency and profitability are the objectives of poultry production. Investigating allocative efficiency of feeds will bring development to the poultry industry in Nigeria. Using a set of structured questionnaire, primary data were collected from 60 poultry farmers (30 broiler farmers and 30 layer farmers). Collected data were analyzed using a combination of descriptive and inferential statistics (regression model), convectional profit model and feed use efficiency model. The result revealed that the shadow price of a 25kg bag of layer mash (N=2498.2) is less than the ruling price (Market price) of N2500 by N1.8. The result further shows a shadow price of N1991.4. for broiler mash. This is less than the ruling price (market price) of N2000 by N8.6. That at the ruling price of feeds, egg producers and broiler producers should decrease the quantity of feeds consumed per bird and that farmers should buy feeds directly through cooperatives from feed producing companies to enjoy the advantage of price efficiency.

Abstract: The Huanghe River is the main water source in Northwest China and North China,and it has huge effect on the economic development of these areas.The shadow price method is adopted in the paper,which divides the Huanghe River into four sections on the basis of its actual conditions,develops and solves the linear programming model of the optimizing allocation of valley water resources,than gains the shadow price of water resources in each sector of every section.This shadow price is the theoretical value of water resources.
Calculation and Analysis of the Value of Water Resources of Huaihe River

ZHU Jiu-long,TAO Xiao-yan,WANG Shi-jun,TONG Jin-ping,

自然资源学报 , 2005,
Abstract: The Huaihe River running through the eastern part of China is the main water source of the five provinces of Hubei,Henan,Anhui,Shandong and Jiangsu,and has great effect on the economic development of these regions.In this study,the Huaihe River is divided into five reaches according to the actual conditions of the river basin.The shadow price of water resources,that is theoretical water resources value for different water use departments in each channel reach is obtained by means of developing and seeking solutions of the model for optimizing allocation of the basin's water resources,which can provide scientific basis for the formulation of the level of water resources value of Huaihe River.
The Nonparametric DEA Models for Resource Allocation

HAN Song,WEI Quan,|ling,

系统工程理论与实践 , 2002,
Abstract: The frontiers analysis has more and more applications to economic problems and the nonparametric methodology is one important analysis method in this field. This paper gives resource allocation models with cone structure, and also analyses economics problems with the Data Envelopment Analysis (DEA) nonparametric method. Comparing the traditional methods, we can not only obtain the same results by this method, but also get richer economic and management information. Therefore, the nonparametric DEA models have special advantage for dealing with economic problems.
Calculation of Chinese Shadow Price of Water Resource Based on Dynamic Computable Equilibrium Models

HE Jing~,

系统工程理论与实践 , 2005,
Abstract: This paper put forward a new approach based on the dynamic input-output optimizing model to solve the problem on the optimized allocation of water resource through long-period span. Firstly, we bring forward the nonlinear dynamic input-output optimizing model concerning the broad-sense shadow price. Secondly, we bring forward the calculation approach and the process. Lastly, by using the 1999 Input Output 33 sectors water resource tables in China and 9 major rivers tables, we bring forward the result of shadow price 1949-2050 in China and 9 major rivers.

Abstract: In land utilization planning, to calculate the shadow price of the linear planning result may determine for the objective function (S) the additional contribution value produced by the result at the time of optimus state and when certain limiting condition (aijxi=bi) is relaxed. On the other hand, the sensitivity analysis solves the permitted feasible change scope of the resource restriction quantity (bi) and the benefit coefficient (ci). Here the change scope is brought about by the change of market situation and production process under the condition that the linear planning still keeps the optimum solution. As the above mentioned calculation and analysis, the static linear planning model is made to move a step forward toward the direction of the dynamic model. This expands the realm for it to be popularized and applied in a certain place and at a certain time.
