Graph Theory Matrix Approach with Fuzzy Set Theory for Optimization of Operating Parameters on a Diesel Engine Abstract In this paper, Graph theory and matrix approach is explained in detail to show how it serves as a decision making and analysis tool with interdependent relationship framework. The desirable properties of graph theory and matrix approach are ability to model criteria interactions and ability to generate hierarchical models for modelling and solving complex decision making problems. This methodology is adopted to find the optimal combination of operating parameters on a diesel engine. For in-depth analysis of the methodology, Fuzzy set theory with crisp and fuzzy values are also incorporated and solved. 1. Introduction …show more content…
In this paper, Graph theory matrix approach (GTMA) with Fuzzy set theory is adopted to find the optimal amalgamation of diesel engine operating parameters i.e., Load, Injection timing and Injection pressure predicated on the performance and emission parameters. Graph theory matrix approach has the facility to model interactions, structure quandaries hierarchically, Adil Baykasoglu [2]. 2 Graph Theory Matrix Approach Graph theoretic model is a multifarious implement, Tutte[3]. It is utilized in sundry applications to analyse the system up to the component level. The graph theoretic approach is divided into three terms: Digraph representation Matrix representation Permanent function representation 2.1 Digraph Representation If in a graph G (V,E), each edge e Є E is associated with an authoritatively mandated pair of vertices, then G is called a directed graph. A directed graph is verbally expressed to be vigorously connected, if there is a path from Vi to Vj and any dyad of vertices of the graph, for a directed graph to be vigorously connected, there must be
Dodge want to make a diesel engine that was light still had power and also great fuel economy
...analyze multiple criteria ranking problems based on the proposed case-based distance models is shown in Figure 3.2. It includes the following steps:
85% equipments use single-cylinder diesel engines, while the rest use multi-cylinder ones. In the market of multi-cylinder diesel the competition is less intense because of excessive demand. The prospect is much more promising. Longxi has a certain competitive advantage in this market, resulting from its popular product such as SL2100.
Mesa’s Foundation Trust (MFT) is a medical provider that provides services to patients. MFT wants to reduce the amount of resources that were provider by several other facilities. During this consolidation MFT’s goal to continue to provide the same types of service and without impacting the amount of time. The need for a decision support system that can not only maintain the historical data, but also capture new data for analyzing. Based on the needs IT support must build the DSS to handle semi-structured problems. The decisions that are made based on given data are standard, but there will always be problems that fall outside the norm (Turban, Sharda, & Delen, 2011). There will be data that is known, but there will also be the unknown. The data should be gathered into a database that can provide management the ability to analyze. The system must be able to collect the given data and an process the information in a format that is understanding to the decision makers. Within the data driven model of the decision support system, the staff at the facility can quickly attend to the patients. Data must be accessible to all the associated medical facilities for MF...
With new diesel technology in today’s world, I think people should consider trying or using new diesel cars and trucks as well as the use of clean diesel.
This involves relating total head, horsepower input, efficiency, and NPSH as a function of pumping capacity (in gpm), similar to Figure 3-36A (Lab Manual).
In my undergraduate years, I have acquired a strong background in the fundamentals of basic mechanical engineering, having studied subjects such as Strength of Materials, Thermodynamics, Fluid Mechanics, Heat and Mass Transfer, Design of Machine Elements and Automobile Engineering. Whilst pursuing my diploma & degree courses, my interest for Automotive Engineering grew even more having learnt more on the different types of internal combustion engines, their configuration and importance. However, what I lacked was a practical understanding on these core areas of Automotive Engineering. To gain a better understandi...
Use appropriate tools that support data gathering (e.g. affinity diagram, brainstorming, fishbone, flowchart, force field, how-how, interrelationship digraph)
Matrix structure is first introduced in the aerospace industry in the 1960s and become one of the popular organizational design options in today’s business and industry (Derven & Alexandria, 2010). Burns and Wholey (1993) poinited out that matrix structure were used in advertising agencies, aerospace firms, research and development laboratories, hospitals, government agencies, and universities. Matrix structure is the combination of two or more different structures and take the advantages of the pure functional structure and the product organizational structure (Robbins & Judge, 2011, p. 497). The employees in the matrix may have two bosses: their functional department managers and their product managers. For example, all engineers may be in one engineering department and report to an engineering manager, but these same engineers may be assigned to different projects and report to a project manager while working on that project. In many organizations, a matrix structure is implemented to address the requirement to do more with less and become more agile. The matrix structure, which focuses on horizontal as well as vertical management, has become more widespread as a result of globalization and the...
To Begin to understand Social Network theory more deeply, it is important to understand some of the key concepts of the theory. One of the main concepts of this theory is identifying what a network means. A network can be defined as a set of relationships (Dunn, 1983). The simplest kind of network contains two objects, such as two people, and a relationship that links them together. For example, two people that know each other would ...
Most people today fill up their car with different qualities of petrol, because that's what the average car takes. They don't usually consider an alternative for the petrol that they load into their cars. Although petrol is widely used, it is not the only source for a car to get its power from; diesel and electricity are alternatives to the general petrol used by most cars. Although different from each other, diesel and electricity are alternatives to the average gasoline received at a gas station. Diesel is a more concentrated type of fuel that is usually used by big automobiles because they require a lot of power in a little amount of time. Electricity is a method that uses the power of batteries to produce a low horsepower but, nevertheless fast automobile. Electric cars are generally created to be soundless and environment friendly. The purpose of this paper is to classify and educate the reader of the different types of fuel available for an automobile to use: petrol, diesel, and electricity. The general petrol, used by most people, is usually the only type of fuel accepted on the average car in the United States today.
According to the School of Information Sciences and Technology at Penn State University, the Rational Model of decision-making, “requires comprehensive problem definition, an exhaustive search for alternatives, and thorough data collection and analysis. According to this model, information exchange and communication are unbiased, and accurate decision alternativ...
Diesel engines are an important component of society in how they are used efficiently and effectively. Diesel engines have been around since 1892 when inventor Rudolph Diesel was able to achieve his goal of developing an internal combustion engine that can achieve maximum efficiency as seen in the Carnot Theorem. The Carnot Theorem set the standard for determining the maximum
Some decisions prove to be vital and any miscalculation that may be involved may prove dire for the individual or the organization. In identifying the criterion to use while evaluating different decisions, many factors pertaining the structure should be considered. The pros and cons of every decision made should be evaluated to ensure that the option chosen has the most positive effect on the individual and the organization. Some of the activities that may require keen decision making include project development, finance and operations. With the knowledge attained it will be easier to cope with tough decisions that may come up in my career. Decision making models may be generated to give an in depth view to the problem and also provide critical analysis ability. It is also vital noting that for those in managerial positions, they face a bigger task in decision making. A good understanding of the business function and structure will provide an in depth knowhow to those that have studied the
Since nodes themselves are not relied upon for communication, the failure of a single node is not problematic for the rest of the network. For a major issue to occur, there must be a problem with the bus itself. Despite its simplicity and reliability, the bus network does have several limitations. The cable length of the bus is limited due to data loss. Also, a bus network may have performance issues if the nodes are located at scattered points and do not lie near a common line....
