This qualitative descriptive research aimed to describe in detail the meaning of the values of religion and expression of women's resignation batik workers in the struggle of the production process, and the factors that influence it. Research was taken place in Pekalongan city and data obtained through observation, interviews, and literary studies. The results showed that deep belief in God is the foundation of understanding of the value of religion in the world of work as well when they interact with the skipper and other workers. The expression of resignation is seen almost in all stages from raw material procurement, production to marketing. Surrender women sanggan also evident in labor relations and outside the employment relationship, which is due to the fact that the religious elite is skipper and social conditions of patriarchal religious culture.

This study discusses the application of the material requirements planning (MRP) method in the planning of raw materials in a furniture company. The purpose of this research is to know the planning of raw materials for furniture products in UD. AA, determine the most suitable inventory model to be applied to material inventory planning and analyze the role of the MRP system in raw material procurement planning. The forecasting method used is the quantitative method of time series analysis, determining the master production schedule, calculating lot sizing (LFL, EOQ, POQ methods). From determining the Master Production Schedule, it is found that the cabinet production plan for the next three months is 4 units per period or week, and based on the calculation of Material Requirement Planning (MRP) it can be seen what components are needed for the manufacture of cabinets, how many and when each component is required. Therefore it is obtained that the total raw material requirement for wood for the next three months is 11.34 m³.

Similarities And Differences

This paper provides an overview of our current knowledge about the transformation towards the Neolithic in western Anatolia and the Aegean, and offers a narrative for their interpretation. Within the longue durée perspective of the long revolution in the Near East, the first millennia of the Holocene of the Aegean and western Anatolia are contrasted with each other. Economic strategies, environmental conditions, technologies, raw material procurement and cultural practices in the Aegean Mesolithic and the Pre-Neolithic times in western Anatolia are analysed to classify potential similarities and differences. The evidence of new cultural and symbolic practices, eco-nomies, and technologies in the seventh millennium is discussed as the paradox of a short revolu-tion embedded in a long-term process of interaction, knowledge-transfer and adaptation, setting the scene for the Neolithic pioneers establishing a new social life.

Increases in environmental problems require companies to be more aware towards the environment and take precautions regarding the problems. As a result, companies have started to embrace the concept of green supply chain which includes environmental issues rather than the concept of supply chain which is based on profitability. Green supply chain (GSC) has emerged as an important component of the environmental and supply chain strategies. In order to make a supply chain green, it is necessary to consider all activities in the supply chain such as raw material procurement, inbound logistics, transformation, outbound logistics, marketing, after-sales and appropriate product disposal. This paper aims to review different GSCM dimensions in the literature by explaining green supply chain concept and address the activities/practises that can be used to ensure these dimensions are green.

This chapter is partly based upon the results of the ARCHGLASS project, which analysed samples dating from the middle of the first millennium BC to the ninth century AD. With the introduction of Greco-Roman translucent glass, colour separation and control over the properties of a re-molten batch become much easier. Once the benefits of glass recycling in terms of raw material procurement, energy expenditure, and waste management are clear, the collection and reuse of cullet becomes common in the Roman world. It is estimated here that upwards from a quarter of the glass circulating in the Roman to early Byzantine economy at any time constitutes recycled glass. It is hypothesized that, apart from the possible addition of cullet to tank furnaces, glass recycling would have been a small-scale process, at the level of the individual workshop.

Game Simulation

This chapter reviews the potential benefits and challenges of knowledge-based computer game simulation as means of understanding the dynamics of global procurement and manufacturing supply chains. In particular the chapter focuses on the use of software agents to assist decision making across the supply chain, for example in raw material procurement. The chapter describes a framework for supply chain scenarios in multi-agent based simulation games. The agents' behaviour is governed by business rules, based on the concept of normative knowledge representation and its reasoning mechanism (known as rule-based reasoning, RBR) and that also come closer to the task that confronts the supply chain operational manager – the analysis of current case in hand in terms of previously decided business problem solutions, known as case-based reasoning (CBR). The aim is to introduce more realistic behavior of the supply chain actors and improve understanding in operational management of supply chains.
