Aspects for green manufacturing and process planning
In it we want to provide an effective approach to assist manufacturers to choose between realistic alternatives on the shop floor for Green Manufacturing, we have to consider all the aspects of green manufacturing such as decision-making problem set, decision-making objectives and their mapping relationship. The considerations in traditional decision-making of manufacturing processes planning are mainly quality, time and cost. But from the point of Green Manufacturing, the factors of resource consumption and environmental impact are also considered.
INTRODUCTION
In modern trends as all the manufacturing industries are focusing on three aspects that are quality ,cost and time but with these aspects they also have to consider environmental aspect and resourses consumption.As Green Manufacturing is a modern manufacturing mode which has the goal of designing and delivering products that minimize negative effects on the environment, while also trying to maximize resource efficiency through their use, production or disposal. In spite of the various factors (legislations, standards, publicity, even competitiveness enhancement, etc.) encouraging the introduction of Green Manufacturing, it has not seen widespread usage and implementation in firms. Machining process planning for Green Manufacturing, also known as environmentally clean machining process In green manufacturing mainly planning focuses on the reduction of environmental impact on the shop floor through the optimum of process plan. So it is important to consider all the aspects which assist manufacturers to choose between realistic alternatives, such as tools of the Green Manufacturing. The considerations in traditional manuf...

... and their mapping relationship. The factors of time (T), quality (Q), cost(C), resource consumption(RC), and environmental impact (EI) are considered together as the process planning objectives. The consideration embodies the balance of economic profit and environmental performance.
A new algorithm named as Grey Analytic Hierarchy Process is presented to handle the upward model. This algorithm integrates Grey Relation Analysis and Analytic Hierarchy Process together.GRA is used to handle the relativities between the five process planning objectives, and the problem of muti-objective and multi-schemes. Analytic Hierarchy Process (AHP) is used to obtain the weights between indexes.
The feasibility and effectiveness of the proposed model and algorithm are illustrated and shown though a practical case of the selection of a machines for Green Manufacturing.

In today’s operational management arena, there are certain expectations from a managerial aspect that must be met in order to be successful. A comprehensive look at the Space Age Furniture Company will show exactly what the Materials Requirement Planning (MRP) calculations are for this company at present time and then take the information given in order to properly suggest ways to improve the sub-assemblies. In addition, there will be an analysis on the trade-offs between the overtime and inventory costs. A calculation will be made on the new MRP that will improve the base MRP. This paper will also compare and contrast the types of production processing to include the job shop, batch, repetitive, or continuous, and determine which the primary mode of operation should be and exactly why. A detailed description on how management can keep track of the job status and location during production will also be addressed. Finally, there will be a recommendation on they type of changes that need to occur that will be beneficial to the company and at the same time add value to the customer. This paper will conclude with summary of the major points.
The first metric will focus on their understanding how well their global factories are adapting to a more energy efficient system and determine whether or not the steps they are taking are adequate enough to determine success or failure. The second metric is focused on understanding their product’s ecological and environmental impact; essentially determining what type of waste is left through manufacturing and selling their products. It is with the understanding that the manufacturing of goods is not the end of the process, but rather the start of a full cycle of creating a sustainable company. The last metric is focused on employee participation, their
This scenario, a low-urgency issue as a middle manager at a company, seems particularly useful as it is a position that many of us might find ourselves in upon graduation. We are thrown into the scenario with an average amount of surface information. In this exercise, we were faced with the challenges related to implementing an organization-wide sustainability initiative, to which we face some resistance. The plan sought to change the amount of raw material inputs to make Spectrum's sunglasses more ecologically friendly, as well as address the company’s current env...
Inputs to quality planning will include: the scope baseline, the individual project requirements that, when taken together, constitute the full project scope; the stakeholder register which identifies those individuals who will actively contribute to the execution of the QP and who therefore need to be involved in quality planning; cost and schedule baselines which have a cascading effect on project scope; and, the risk register, which details the areas of risk that are related to quality and that may affect the planning process. Finally, we will also integrate the tenets of our quality p...
The purpose of this paper is to create a sustainable solution paper (SSP) for Pep Boys’ Automotive Inc. otherwise known as Pep Boys parts, tires and service, is part of the automotive aftermarket retail parts and service industry. Since 1921, Pep Boys have been in business (The Pep Boys--Manny, Moe & Jack SWOT Analysis, 2015). Consequently, Pep Boys operates over 800 stores and 7,400 service bays across the country and Puerto Rico while also employing over 20,000 associates (The Pep Boys--Manny, Moe & Jack SWOT Analysis, 2015).
Environment is another significant factor that affects the strategic plan. When a major environmental disaster occurs, such as a hurricane, it can affect a company’s production facilities, their sales facilities and the community that the company serves.
Going green in the workplace is a new trend in business. In choosing to go green in the workplace you may be challenged by an elevated initial start-up costs, however savings earned from this investment will more than pay for those initial costs in the future. Many people see this as a controversial issue, and granted it does have its own unique set of pro and cons, but if a business makes careful choices going green can prove to be very rewarding. Companies are doing this to save money on energy expenses as well as deploying it as a means to help reduce the carbon foot-print they are leaving behind.
Environmental pressures have caused green supply chain management to emerge as an important corporate environmental strategy for organisations’ processes. Our discussion will describe, illustrate and critically evaluate the purchasing process of Woolworths. It will further identify the steps of the purchasing process, the effect of green purchasing and sustainable purchasing. Moreover, the essay will go on to look at the effort that Woolworths has made through their programmes and initiatives of green purchasing.
Currently there is an urgent need to make products and processes sustainable, and beneficial to everyone and everything. This is because the true facts are that if we do not act now, our resources will run out and we wont be able to do anything about it. We must now design for the future and not our currents needs, and everything should be compatible with nature to correspond with sustainability. The question designers should be asking themselves now is ‘is this design choice moving us in the right direction?’
The waste management of a manufacturing company is one of the environmental matters that is mostly concerned by the society. The costs to manage the wastes from production could be very costly to a manufacturing company. Nevertheless, by using ABC system, a company can manage the production wastes in an effective and efficient manner. ABC system provides a road map to the cost reductions on waste management (Joseph & Thomas, 1995). It provides the activity-based information for the management to make better business decisions around sustainability and profit. An example would be Safety-Kleen corporation, a waste-recycling company who wanted to find an alternative to removing and recycle the hazardous wastes at a cost efficient way. It introduced ABC system into its organisation and successfully save costs in its waste management operation. The activity of transfer wastes from the collection points to the vehicles and to the disposal sites can be traced by the ABC system (Joseph & Thomas, 1995). In this way, ABC system helps to facilitate the cost measurement and provides management with accurate cost information of each activity involved in the process to make optimal decisions. Hence, with the utilisation of ABC system, it would help an organisation to have better cost control and management to support its sustainability interests on environmental
Therefore, to determine the material handling system is very important for reduce cost and increased profits. The fact material handling systems represent a major part of the total manufacturing cost make necessity to choose adequately the material handling system when a manufacturing system is designed. One of the most successful applications of experts systems is selection of equipment for material handling (SEMH). SEMH lookups the knowledge bottom to be able to suggest the degree associated with mechanization, and also the type of product coping with equipment to become utilized, according to some traits. Fisher, Farber, and Kay (1998) have introduced MATHES: material handling equipment selection expert systems for the selection of a material handling equipment from 16 possible choices. MATHES as well as 172 principles takes course, product stream quantity, product sizing's in addition to distance concerning sectors because variables. Swaminathan, Matson, and Mellichamp (1992) have developed EXCITE: expert consultant for in-plant transportation equipment addressing 35 equipment
In this environment conscious world, there is a growing argument about the ways in which a business should run its activities that should not have any negative impact on the environment overall. Raderbauer, M. (2011) A research done at the University of Exeter indicated that Industry has been the perpetrator behind ruining the environment for fulfilling its short-term profits instead of long-term environment consequences. Many businesses have understood the importance of preserving the environment and thus it is in the betterment of its own business, keeping in mind the long-term profits they can have while making environment responsible decisions. Business are more affected by environment because they run with the help of all the raw materials
Implementation of green concepts has been significant not only in design engineering but also in construction. Therefore the knowledge about green design has been a very important fact for the sustainable development in civil engineering. Concepts such as green buildings, carbon foot print, ecological foot print and LEED rating system have helped to achieve sustainable development for civil engineering
