Bridging the Gap between Network and Project Selection Levels in Pavement Management

Gurganus, Charles Felder 2011 May 1900 (has links)
Pavement management is one of the primary responsibilities for departments of transportation and other municipalities across the country. Efficient and proper use of taxpayer dollars to preserve and improve the existing transportation system has never been more important due to the current fiscal environment. Agencies use pavement management systems to store data describing the state of the network. This information is often used to help make decisions regarding the location of pavement preservation actions. There is often a discrepancy between the need estimates of network-level pavement management systems and where and how pavement preservation and improvement dollars are actually spent (i.e., actual pavement preservation and improvement projects). This research focuses on evaluating the Texas Department of Transportation’s (TxDOT) Pavement Management Information System (PMIS) to assess the agreement between its need estimates and actual construction projects at the district level. The research revealed there is little agreement between the output of PMIS’s Needs Estimate tool and actual construction projects. Possible reasons for this disagreement include the inability of PMIS’s Needs Estimates to consider the decision makers preferences and priorities, and also its inability to consider multiple years of condition data simultaneously. Through the use of the Analytic Hierarchy Process (AHP), the research was able to capture the effect of several variables on the decision making process. Using this method, pavement project suggestions were created that more closely matched actual projects than what the current Needs Estimate tool suggests. The projects selected using the new method were then tested against actual construction within three counties of the Bryan district. The new method closely matches actual preservation decisions made by the district within these three counties.

Control and Management Strategy of Autonomous Vehicle Functions

Kim, Chang Won 2010 December 1900 (has links)
In this research, an autonomous vehicle function management methodology is studied. In accordance with the traffic situation, the decision making level chooses the optimal function that guarantees safety and minimizes fuel consumption while the control level is implemented via neuromorphic strategy based on the brain limbic system. To realize the decision making strategy, the Analytic Hierarchy Process (AHP) is used by considering driving safety, driving speed, and fuel efficiency as the objectives. According to the traffic situation and predefined driving mode, Lane Change Maneuver (LCM) and Adaptive Cruise Control (ACC) are chosen as the alternative functions in the AHP framework. The adaptive AHP is utilized to cope with dynamically changing traffic environment. The proposed adaptive AHP algorithm provides an optimal relative importance matrix that is essential to make decisions under a varying traffic situation and driving modes. The simulation results show that proposed autonomous vehicle function management structure produces optimal decisions that satisfy the driving preference. The stability of BLS based control is also investigated via Cell-to-Cell Mapping. In this research, autonomous vehicle functions such as Lane change maneuver and Adaptive cruise control are developed by means of BLS based control. The simulation results considered various traffic situations that an autonomous vehicle can encounter. To demonstrate the suggested control method Cell-to-Cell Mapping is utilized. Subsequently, the autonomous vehicle function management strategy is developed by Applying AHP and an adaptive AHP strategy is developed to cope with various traffic situations and driving modes. The suggested method is verified numerical simulations.

The study of key seccess factors for applying the profit center in the construction industry - The case study of a construction company in southern Taiwan.

Shen, Heng-su 04 January 2005 (has links)
Since Porfit Center had been applied in DuPont Company in 1920, it has become a popular business model which emphasized on elevating employees¡¦ self-commitment by sharing company¡¦s profit and has been adopted by companies around the world. For the construction industry in Taiwan, due to the decline of real estate market, the deflation of national construction plans and the action of joining into WTO, most construction companies are experiencing their difficult time and therefore are eager to make some changes. Profit Center then has been regarded as a helpful construction management tool to achieve higher performance. This thesis is a case study for a construction company that locates in southern Taiwan and is planning to introduce Profit Center into its system to improve its performance. This thesis follows Habitual Domains¡]HD¡^theory and Analytic Hierarchy Process ¡]AHP¡^method to create the key success factors ¡]KSF¡^for the case company, and a priority list that rankes by the weight index is built at the end of this thesis. To allocate their resource more efficiently for applying the Profit Center, a construction company is suggested to build its own key success factors based on the perspective of construction industry. That is, unlike emphasizing on hwo to share profit as other industries are used to, this study discovered that because high risks and frequent design¡¦s variation might greatly affect the cost of a construction project, the Profit Center in a construction firm is required to focus on how to keep encouraging its employees if the profit of the project is diminished due to the reasons as aforesaid.

Using Analytic Hierarchy Process to Construct a Performance Evaluation Model for Assessment of Direct Labor in the Paper Mill.

Chang, Yu-Hsien 21 June 2005 (has links)
Through decades of development along the thriving economy, the paper mill industry in Taiwan has had substantial growth in both quality and quantity. However, the rising trend of corporate digitalization and paperless information transmission in recent years brought the paper industry a never-before-seen impact. Therefore, this research approaches the subject from the aspect of constructing a performance evaluation model for assessment of direct labor in the paper mill industry by using the Analytic Hierarchy Process (AHP), in expectation to provide a set of more subjective evaluation model to replace the objective, impression-based evaluation method traditionally used in the dominatingly small and medium enterprise centered paper mill industry. A subjective evaluation system will provide evaluated employees information on their performance and development; through such method, the company will be able to strengthen employees¡¦ core abilities and further upgrade the company¡¦s competitiveness to achieve the goal of sustainable development. Subjects of this research are 108 member companies of the Taiwan Paper Mill Industry Association. The survey study were conducted in two stages: The first stage focused on significance analysis; in which indicators that do not have significance to the performance of direct labor in the paper mill industry are deleted. The second stage interviewed 52 companies that are currently implementing performance evaluation systems. The screened performance evaluation indicators are then calculated by the Analytic Hierarchy Process to derive their relative importance and weight. Through analysis of the Analytic Hierarchy Process, we derived an evaluation form for assessment of direct labor in the paper mill industry. Through further study, we discovered that in the performance evaluation dimensions, the work performance dimension has the highest relative importance, professional knowledge/abilities second and personal quality last. Since the full evaluation developed in this research are statistically based, it can be not only provided as a reference for evaluation activities but also converted into an internal audit system for regular evaluation and perpetual improvement to constantly reinforce the company¡¦s competitiveness. This research was also implemented on a target case for empirical study. In which, an actual evaluation with the model developed in this study was carried out. Results of the performance evaluation were highly affirmed by the higher-level management of the experimented company. They consider that this evaluation model is highly interpretative and can be used for future performance evaluation.

Su, Tsang-Ming 01 July 2005 (has links)
Capability Maturity Model Integrated (CMMI) developed by Software Engineering Institute of Carnegie Mellon University is aimed to improve the productivity of software development. From CMM to CMMI, they have been adopted worldwide. But the large numbers of unsuccessful and/or painful implementations have proved these implementations easier said than done. The software industry in Taiwan faces the challenge of global competition. Continuous improvement of productivity becomes inevitable. To achieve this goal, recently, government and non-government organizations together promote the CMMI. This thesis focuses on the Decision Analysis and Resolution of CMMI Level 3. Through the design of related methods and the development of software tools, the decision process can be more structured and more effective. Potential applications include evaluation and selection of software and hardware, outsourcing partner, tools, risk resolution alternatives or people. The typical Go/No-Go decision can also fit into it. The decision analysis methods included in this research are Multi-attribute Decision Making and Analytic Hierarchy Process(AHP). In addition, alternative screening and group decision making can be integrated into the above methods.

HSIAO, YUAN-LIN 01 August 2005 (has links)
Abstract There have been lots of M&A, alliance and restructuring activities occurred in the chemical industry all over the world since 2001. In order to operate the business successfully, the best way is through innovation instead of taking restructuring, cost down and/or M&A strategy only. Usually, chemical material should be well mixed or prepared to get unique properties for application. R&D and innovation are the good solutions. Under such circumstances, in order to win the game and even to survive, the chemical firms need to make changes of their products to be more value-added and keep their sustaining competitive advantages . This study has surveyed the questionnaires which were answered from the high value-added chemical firms, government, educational and research institutes. Analytic Hierarchy Process (AHP) was adopted for analysis. Our findings are: 1. The ratings of the importance in the second level of AHP are: ¡]1¡^The members participating in the innovation ¡]2¡^Organization system ¡]3¡^Protection of innovation ¡]4¡^Environment of the firm 2. The top five important factors in the third level of AHP are: ¡]1¡^Opinions from the industry---communication ability of the R&D director, firm secrecy protection mechanism, CTO can make the consequences of decisions for R&D innovation activities to take, relationship between firms and customers, participation of the R&D director in corporate strategy formulation ¡]2¡^Opinions from the government, educational and research institutes--- organizational culture of supporting venture and tolerating mistakes in the innovation process, CTO can make the consequences of decisions for R&D innovation activities to take, communication ability of the R&D director, firm secrecy protection mechanism, participation of the R&D director in corporate strategy formulation ¡]3¡^Opinions from the industry, government, educational and research institutes--- communication ability of the R&D director, firm secrecy protection mechanism, CTO can make the consequences of decisions for R&D innovation activities to take, participation of the R&D director in corporate strategy formulation ,organizational culture of supporting venture and tolerating mistakes

Decision Factors in Patients Receiving Cutaneous Laser and Intense Pulsed Light Treatment for Aesthetic Purposes

Tzung, Tien-Yi 18 August 2005 (has links)
Cutaneous laser and intense pulsed light treatments are two of the most popular aesthetic treatment modalities. More and more physicians regardless of their training background are providing such profitable services because there is still no regulation on the cosmetic procedures a physician can perform. The purpose of the present study was to find out the relative strength and weakness of different medical specialties in providing laser and intense pulsed light treatment. Major decision factors for physician selection were extracted from 19 physician choice criteria with factor analysis. Using analytic hierarchy process, the relative weight of these factors and that of dermatologists, plastic surgeons and aesthetic practitioners in each factor were calculated. After reading the training curricula of dermatologists and plastic surgeons, respondents were asked to rate again the 3 medical specialties. Our results indicated that medical competence (0.3296) was the most important major decision factor followed by recommendation (0.2198), friendliness (0.1350), cost (0.1307), complete service (0.0984) and physical attribute of the physician (0.0865). Compared with plastic surgeons and aesthetic practitioners, dermatologists had an advantage in all factors except complete service, which was the strength of plastic surgeons. New patients, aged under 40, with a college degree and a monthly allowance less than 20000 NTD were more likely to change their rating in favor of dermatologists after reading the curriculum profile..
