Methodology and tools for improving competence of a chemical plant characterized by a complex Supply Chain network

Supply chain performance is strongly influenced by its design, chosen architecture, logistic network and types of finished product that made their marketplace. Sometimes environmental reasons like site location due to deals between government administration and companies may cause changes in logical design and hence increase logistic network complexity and become in a strategic Supply Chain constraint. Our case study addresses a geographic place of a chemical manufacturing plant inside its supply chain which the 86% of the domestic raw material suppliers, its unique distribution center and 100% of the plastic and metallic packaging suppliers are placed over 800 kilometers of distance. Starting from this restriction the research work consists in how redesign and rethink the architecture of the existing supply chain and optimize the processes inside the chemical plant trying to minimize the cost disadvantages related directly to the physical location of the factory. This research treats the selection of coordination and collaborative mechanisms between supply chain members, other company departments and outsourcing partners in order to create a collaborative coordinated model for optimization of this complex supply chain network. Besides this environment limitation, the most salient threats were internal at the company and consisted successfully implement coordinated actions to improve the management of processes and to take practical level. Fighting against the cultural change of the sectors involved and achieves the proposed expected results. The thesis consists of five practical cases studies of coordinated process for performance improvement. Each one being part of an integrated system that converges in a Plant performance common goal, which is increase supply chain competence. RQ1 tries to identify the processes which will be possible to apply the SC new model and management system emerged from the theoretical study and practical benchmarking cases. The research design is then presented by the implementation at Plant’s field level of the proposed develop scheme using the coordinated collaborative improvement model. RQ2 asks whether the chosen cases are adequate. Selecting the best alternative proposed for each thread. After that, the obtained results are presented and discussed for each field case. The focus of the research study is on supply chain practice and supply chain theoretical framework also. To conclude with the author experience that remarks supply chain practice has been heavily influenced by supply chain research and vice versa

A Development Framework to Determine the Applicability of a Dry Port to Fremantle Port Supply Chains: a Case Study

Fremantle Ports’ landside container transport has environmental and social impacts and, through congestion, reduces the efficiency of its hinterland links. Incorporating dry ports into supply chains can reduce these impacts and increase seaport capacity and effective life. Using dry port characteristics, common criteria and development theory with a Fremantle Ports case study and user survey, a dry port development framework is established and validated. The framework demonstrates a dry port's role in Fremantle Ports operations

COBE's search for structure in the Big Bang

The launch of Cosmic Background Explorer (COBE) and the definition of Earth Observing System (EOS) are two of the major events at NASA-Goddard. The three experiments contained in COBE (Differential Microwave Radiometer (DMR), Far Infrared Absolute Spectrophotometer (FIRAS), and Diffuse Infrared Background Experiment (DIRBE)) are very important in measuring the big bang. DMR measures the isotropy of the cosmic background (direction of the radiation). FIRAS looks at the spectrum over the whole sky, searching for deviations, and DIRBE operates in the infrared part of the spectrum gathering evidence of the earliest galaxy formation. By special techniques, the radiation coming from the solar system will be distinguished from that of extragalactic origin. Unique graphics will be used to represent the temperature of the emitting material. A cosmic event will be modeled of such importance that it will affect cosmological theory for generations to come. EOS will monitor changes in the Earth's geophysics during a whole solar color cycle

SIMAID: a rapid development methodology for the design of acyclic, bufferless, multi-process and mixed model agile production facilities for spaceframe vehicles

The facility layout problem (FL) is a non-linear, NP-complete problem whose complexity is derived from the vast solution space generated by multiple variables and interdependent factors. For reconfigurable, agile facilities the problem is compounded by parallelism (simultaneity of operations) and scheduling issues. Previous work has either concentrated on conventional (linear or branched) facility layout design, or has not considered the issues of agile, reconfigurable facilities and scheduling. This work is the first comprehensive methodology incorporating the design and scheduling of parallel cellular facilities for the purpose of easy and rapid reconfiguration in the increasingly demanding world of agile manufacturing. A novel three-stage algorithm is described for the design of acyclic (asynchronous), bufferless, parallel, multi-process and mixed-model production facilities for spaceframe-based vehicles. Data input begins with vehicle part processing and volume requirements from multiple models and includes time, budget and space constraints. The algorithm consists of a powerful combination of a guided cell formation stage, iterative solution improvement searches and design stage scheduling. The improvement iterations utilise a modified (rules-based) Tabu search applied to a constant-flow group technology, while the design stage scheduling is done by the use of genetic algorithms. The objective-based solution optimisation direction is not random but guided, based on measurement criteria from simulation. The end product is the selection and graphic presentation of the best solution out of a database of feasible ones. The case is presented in the form of an executable program and three real world industrial examples are included. The results provide evidence that good solutions can be found to this new type and size of heavily constrained problem within a reasonable amount of time

Best Environmental Management Practice for the Waste Management Sector

The way communities generate and manage their waste plays an absolutely key role in their ability to use resources efficiently. While making European economy more resource efficient and circular requires a large spectrum of actions, a huge potential for saving resources lays in improving waste management at local level in Europe. On the basis of an in-depth analysis of the actions implemented by frontrunner organisations in the waste management sector, this report describes a set of best practices with high potential for broad uptake. They are called Best Environmental Management Practices (BEMPs) and aim to help local authorities in charge of waste management and waste management companies move towards circular economy. The BEMPs, identified in close cooperation with a technical working group comprising experts from the sector, cover the waste management areas which determine the most the overall waste management performance: setting a waste management strategy, promoting waste prevention, establishing an efficient waste collection that supports re-use and recycling, and stimulating waste and product re-use. Certain areas of waste treatment are also covered. The BEMPs address mainly the management of municipal solid waste, but also of construction and demolition waste and healthcare waste. Additionally, the report provides a set of environmental performance indicators that organisations can use to assess their waste management performance and monitor progress as well as benchmarks of excellence that give an indication of the levels achieved by best performers. The report presents a wide range of information (environmental benefits, economics, case studies, references, etc.) for each of the best practices and aims to provide inspiration and guidance to organisations of the sector. In addition, the report will be the technical basis for the development of an EMAS (EU Eco-Management and Audit Scheme) Sectoral Reference Document on Best Environmental Management Practice for the Waste Management sector according to Article 46 of Regulation (EC) No 1221/2009 (EMAS Regulation).JRC.B.5-Circular Economy and Industrial Leadershi

Best Environmental Management Practice for the Car Manufacturing Sector Learning from frontrunners

The European automotive industry is one of the EU's largest manufacturing sectors, and the automotive value chain covers many activities largely carried out within the EU, such as design and engineering, manufacturing, maintenance and repair, and end-of-life vehicle (ELV) handling. This Best Practice report describes Best Environmental Management Practices (BEMPs), i.e. techniques, measures or actions that are implemented by the organisations within the sector which are most advanced in terms of environmental performance in areas such as energy and resource efficiency, emissions, or supply chain management. The BEMPs provide inspirational examples for any organisation within the sector to improve its environmental performance. The report firstly outlines technical information on the contribution of car manufacturing and end-of-life vehicle (ELV) handling to key environmental burdens in the EU, alongside data on the economic relevance of the sector. The second chapter presents best environmental management practice of interest primarily for manufacturing companies (car manufacturers and associated manufacturers in the supply chain) covering cross-cutting issues related to key environmental impacts (such as energy, waste, water management, or biodiversity) before exploring best practice linked to specific topics, such as supply chain management. Subsequently, specific information concerning actors in the treatment of end-of-life vehicles is presented in the third chapter, focussing in particular on best practice applicable to processers of ELVs. This Best Practice Report was developed with support from a Technical Working Group of experts from the car manufacturing and ELV sector and associated fields. The report gives a wide range of information (environmental benefits, economics, indicators, benchmarks, references, etc.) for each of the proposed best practices in order to be a source of inspiration and guidance for any company of the sector wishing to improve environmental performance. In addition, it will be the technical basis for a Sectoral Reference Document on the car manufacturing sector, to be produced by the European Commission according to the EMAS Regulation.JRC.B.5-Circular Economy and Industrial Leadershi
