AN EVALUATION OF SEQUENCING RULES FOR AN ASSEMBLY SHOP

Research relating to sequencing rules in simple job shops has proliferated, but there has not been a corresponding proliferation of research evaluating similar sequencing rules in more complex assembly job shops. In a simple job shop, all operations are performed serially; but an assembly shop encompasses both serial and parallel operations. As a result of the increased complexity of assembly shops, the results associated with the performance of sequencing rules in simple job shops cannot be expected for an assembly shop. In this paper, 11 sequencing rules (some of which are common to simple job shops and some decigned specifically for assembly shops) are evaluated using a simulation analysis of a hypothetical assembly shop. The simulation results are analyzed using an ANOVA procedure that identifies significant differences in the results of several performance measures. Sensitivity analysis also is performed to determine the effect of job structure on the performance of the sequencing rules.     

Exploring the Impact of Delivery Performance on Customer Transaction Volume and Unit Price: Evidence from an Assembly Manufacturing Supply Chain

This study examines the effect of delivery performance on customer transactions. We propose that different delivery performance dimensions (on‐time delivery rate, early delivery inaccuracy, late delivery inaccuracy, and delivery speed) have varying impacts on future customer transaction quantities and unit prices. We further explore the effect of customer types on the proposed relationships. Trade customers (resellers) and Original Equipment Manufacturer (OEM) customers generally have different operational needs for deliveries and therefore may value these metrics differently. Using instrumental variable regression, we analyze a proprietary transaction‐level dataset. The information was compiled by a Fortune 500 manufacturer from its Heating, Ventilation and Air Conditioning (HVAC) control product supply chain, consisting of the manufacturer and its customers. The results indicate that measures of delivery performance affect customer transaction quantity and unit price differently. Furthermore, these impacts can differ significantly between trade customers and OEM customers. These findings provide fine‐grained insights about tuning delivery capabilities to increase sales volume or boost price.

试论马克思主义哲学的辩证本体论

马克思主义哲学包含丰富的唯物辩证的本体论思想,是一种辩证本体论。其中,物质本体论是马克思主义哲学的基础本体论,其宗旨是先行地澄明世界的一般前提和基础;人学本体论是马克思主义哲学的主体本体论、其宗旨是先行地澄明马克思主义哲学研究的核心和主题;实践本体论是马克思主义哲学的逻辑本体论,其宗旨是先行地澄明人类社会历史活动的一般前提和基础;社会存在本体论是马克思主义哲学的结构本体论,其宗旨是先行地澄明人类社会历史的一般本质和特征。

现代本体论视界中的马克思哲学——兼论物质本体论

能否从本体论的角度理解和把握马克思哲学,取决于如何理解本体论。本体论又有传统和现代之别,传统本体论和现代本体论有狭义与广义之分。马克思认为实践就是存在的终极形式、价值的终极基础和认识的终极根源,马克思哲学作为广义的现代本体论是实践本体论。     

Assessing the Measurement and Structure of Material Hardship in the United States

Previous attempts to measure material well-being or hardship have not made clear the relationship of individual items to the broader concept of hardship. The current study used the Survey of Income and Program Participation (SIPP), a large-scale U.S. survey with a large number of questions on the material circumstances of households to create a measurement model of hardship that takes this relationship into account. A higher-order model with five-first-order factors: consumer durables, resources available to meet needs, housing conditions, neighborhood problems and crime, and community services, and a single second-order factor hardship fit the data well, with the “Housing” and “Neighborhood” first-order factors most strongly related to the higher-order hardship construct. Despite our attempts to tie the hardship measures to objective conditions, subjective evaluations were strongly related to most of the factors.

Social Metabolism and Labour in a Local Context: Changing Environmental Relations on Trinket Island

From a material and energetic perspective, this paper outlines the patterns of society-nature interactions of a local horticultural, hunter-and-gatherer population that lives on a remote island between India and Indonesia. Based on empirical research, we present several indicators to show an economic portfolio of a local society that combines horticulture, hunting and gathering activities with elements of industrialisation and market economy. In describing these environmental relations, the study narrows its focus to the use of three socio-ecological concepts, namely socio-economic metabolism, colonising natural processes, and the energetic return on investment. Using these concepts, we show the dynamics of social and environmental transformation at a local level and the consequences this may have for sustainability.
