Abstract:

For resource-constrained project scheduling problems, with aircraft assembly as its background, we established its mathematics model as constraint satisfaction problem. An improved critical path scheduling algorithm is proposed, considering the constraints of precedence relations, resource constraints and space constraints, through the two stages of planning, reaching for aircraft assembly task scheduling optimization objectives. Through the given numerical example results show that, when the objective consists in minimizing the project duration, the algorithm has better performance.

Abstract:

The article investigates the consequences of credit constraints on rural household consumption in China. Based on a unique rural finance and consumption survey, the authors first identify the credit constraint status of rural households from formal financial institutions. Then, they apply an endogenous switching regression model to compare the consumption responses to household production inputs for credit constrained and non-constrained households. The estimation results reveal that the credit constraint could result in the crowding out effect of the aggregate household consumption from its p

The primary objective of this paper is to explore how formal credit constraints affect farmers’ efficiency by the 743 random farmer samples from Jiangxi province in China. The statistic analyses of their individual characteristic, together with the inputs and outputs of their production shows that the constrained value of the production of the credit is RMB 563.2 yuan which is RMB 190 yuan less than those who are not credit constrained. The samples are divided into two groups, the one group with farmers who have been constrained by the formal credit while the other has not. The empirical resul

Abstract:

AbstractIn this article, I propose a phonetically-oriented constraint-based model of speech production that differs from recent approaches in assuming preservation constraints that refer directly to articulatory gestures rather than to perceptual cues. Articulatory gesture preservation constraints interact with a constraint that penalizes the expenditure of articulatory effort. Specific constraints and rankings are projected from a static perceptual knowledge source. Before exploring the model in detail, I address evidence that has been used to argue against precisely this type of “Articulator

Although the global economy requires geological resource mining, production has substantial environmental impacts, including the use of regional available water. In this study, we shed light on the global production capacity of 32 mined geological resources, considering regional water availability as a constraint. We found that current resource mining greatly exceeds regional water constraints for several, notably copper (37% of current production exceeds available water capacity) in 2010. Changing the location of production to regions of lower water stress would alleviate current exceedances

The question considered regards of an admissible production flow organization-guaranteeing completion of the production order under assumed limits, while taking into account the logistics constraints imposed. In that context the approach proposed can be seen as one following the Goldratt’s Theory of Constraints (TOC).

As a cultural practice, however, novelization is hardly known, given its lack of prestige, hence its near-absence in the scholarly fi eld (novelizations seem so „bad” that nobody thinks they deserve any serious interest).

Productivity is at a maximum when the principles of chemistry and genetics allow it to proceed no further, even under ideal environmental conditions. It is often limited by current knowledge, which could be improved through research, by the antagonism between selection criteria, or by economic considerations that make additional productivity unrealistic. Emphasis on increased productivity per se should give way to or at least accommodate improved efficiency of production.

Abstract:

The current investigation primarily delves into the challenges faced by sericulture growers in mulberry and cocoon production. Sericulture, a highly competitive and capital-intensive enterprise, is prevalent across rural and semi-urban areas in India. This industry not only contributes to household income but also generates employment opportunities for entire families, with women actively participating in various facets of sericulture activities. A multistage sampling design was employed to select districts, tehsils, villages, and sericulture growers for the study. Specifically, Beed, Parbhani

Abstract:

This work maximizes oil production from a network of gas lift wells and determines the optimal amount of lift gas with PIPESIM network optimizer. PIPESIM was used to build a couple wellbore-flowline model and its network optimizer was utilized to maximize oil production from a network of gas lifted wells. Two wells were created (Well A and B) and connected to their respective flow lines to a manifold and from the manifold to the central processing facility (CPF) represented by a sink node. A comparison of the oil production rate from Well B with and without constraint on water production rate

Abstract:

Poultry farming is integral part of agriculture in Nepal. The objective of this research was to analyze the prevailing production constraints, characterization of poultry farming and its economic analysis using questionnaire-based survey and on-site investigation. 180 farms were selected from 3 major districts. Garrett’s ranking technique was used to analyze the constraints. Highly significant difference (P<0.01) in size of poultry farm was found. We found significant difference in feeding, housing and drinking system for the chicken. Un-organized chicken marketing channel was observed in t

Abstract:

Although many project portfolio management tools have been developed, little has been found capable of evaluating and managing project quality, cost, and schedule simultaneously. Limited cross-project references also limit lessons learned in the context of triple constraints. This study aims to embed quality check into the earned value management (EVM) method and develop an extended tool for triple constraint management based on EVM. The purpose is to evaluate and manage the triple constraints of a project in one go, incorporating quality management and portfolio management functions into cost
