Therefore, there is a need to study the cause and effect relationships among the processes in government procurement auction. This paper attempts to develop a dynamic model of factors and their relationships in order to explain the phenomena of dwindling bidder size. We have considered factors like number of bidders, bid price qualification level, bid period, work content, and collusion among the bidders to develop a system dynamics model. We suggest that allowable profit margin and work content should be properly designed to get a reasonable number of bidders.

This paper presents such a modeling approach to the strategy formulation of the treatment system in order to economically control effluent quality. First, factorial designs are carried out on the simulation results to identify factors that significantly affect effluent quality. Thereafter, open-loop control (both constant and timevarying), output feedback control, and output-integrated feedback control strategies have been applied. Statistical tests of significance indicate that the strategy of output feedback control has the maximum potential, in both summer and winter, to achieve the dual objectives of maintaining effluent quality within acceptable limits and minimizing aerator energy. Principles Underlying the Activated Sludge Treatment System The process of Activated Sludge Treatment System (Fig. 1) is the most widely employed technique today i...

In this paper, Srinivasan, Mohapatra, and Sahu use the System Dynamics methodology and demonstrate through their model how short-run price movements can be explained. This model may be useful to finance managers who are concerned about the equity issue price for pricing new issues when they go to the capital market. It is also useful to financial institutions interested in buying and selling securities. The authors exhort researchers to develop a unified model combining CAPM and the System Dynamics model to explain long-run and short-run price movements.
Renewable and Sustainable Energy Reviews

The scheme permits, in the monitoring and verification phase, normalisation of the efficiency realisation against unfavourable working conditions. On the one hand, such normalisation brings the energy efficiencies of plants operating in different conditions to a common level, on the other hand, adjustments resulting from normalisation are likely to provide free-riding benefits, and in addition, results in alteration of efficiency realisation. This may be a source of distortion in the market expectation, resulting in trading phase uncertainties. This paper examines the effects of normalisation on the specific energy consumption in the context of the PAT scheme in the coal-based power sector. The paper makes a cross-sectional analysis involving data envelopment analysis and Tobit regression. The results indicate that effect of variation in system demand, planned maintenance time, forced outage, fuel quality, and fuel mix on specific energy consumption is substantial. However, the effect of the variability in coal quality and fuel mix is significantly higher than the other variables. Therefore, use of clean-coal is suggested to stabilise the specific energy consumption for a stable certificate market.

In the case of thermal power plants, investment in energy efficiency projects, using clean coal and buying energy saving certificates are the available compliance options for complying with the scheme. These options are associated with specific forms of cash flows that depend on the uncertain price of energy saving certificates and clean coal premium. This paper uses a Monte Carlo-based decision tree approach to find the optimal compliance options for an efficient and a less efficient thermal power plant. The decision tree evaluates different sequences of compliance options in three consecutive PAT cycles by using the discounted cash flows and their associated probabilities. The study shows that investment in energy efficiency is optimal in the first PAT cycle for the inefficient plant only. The threshold certificate price for the efficient plant is substantially higher than the inefficient plant, implying that the real efficiency improvement is likely to take place in the low-efficiency plants. The study also indicates that the investment in high-efficiency plants is not optimal over a wide range of certificate prices and the incremental cost of clean coal.

The paper presents building of a model, i.e. House of Strategy, out of a two-round Delphi survey, which can be used in strategic planning to develop sets of Goals, Objectives, and Strategies. The survey was made among the stakeholders of the Indian Shrimp Industry in order to set the future goals, and concurrent objectives and to design strategies to achieve them. The first round of Delphi survey resulted into generation of sets of Goal, Objectives, and Strategies. The second round of the survey gathered opinions of survey panelists regarding the desirability and feasibility of the Goals and Objectives, and feasibility and effectiveness of the Strategies. Consensuses of stakeholders opinions on the each of the items with respect to above said criteria were estimated using standard fuzzy consensus building algorithm. Hierarchical representation of a Goal, their corresponding Objectives and Strategies form a tree like structure, called as GOS tree. Seven such GOS trees were developed, each representing a Goal at its top echelon. Validity of each GOS tree was tested using the ratings of the panelists on the goal, objectives, and strategies with respect to the feasibility criterion. The proposed validation process of a GOS tree resulted two set of weights separately for the objectives and the strategies that explained the importance of each of the strategies in achieving the corresponding objective and importance of each of the objectives in aligning towards the goal. These importance weights of the objectives and the strategies were local to the GOS tree. Seven such GOS trees were developed each representing for a future goal. As a strategy might have presence in multiple GOS trees and contributing towards multiple goals, an overall contribution of the strategies was to be found out. We proposed a framework, House of Strategy, which can be used to combine all the GOS trees at one place and could help, in a two-step process, in finding out the overall contribution of each of the strategies towards overall achievement of Industrys goals. The House of Strategy consisted of two sub-Houses, i.e. Goal-Objective (GO) and Objective-Strategy (OS) sub-Houses. In the first step, the GO sub-House calculated the overall priority of each of the Objectives depending on its local importance weights (with respect to each of the GOS tree it represented) and corresponding desirability of the local goal and its own desirability score. Similarly, in the second step, the OS sub-House helped in calculating the overall priority of each of the strategies depending upon the priority of its corresponding objectives (in a GOS tree) as derived by the GO sub-House, its local importance weights (with respect to each of the GOS tree it represented), and its own effectiveness score. Using the House of Strategy, we have prioritized the strategies raised during the Delphi survey. The proposed methodology of building the House of Strategy can be used for designing strategies for an organization/industry using stakeholders' opinion and prioritizing them in order of their overall importance in achieving intended objectives and goals. Furthermore, the House of Strategy can be used as an effective communication tool to portray the goals, objectives, and strategies along with their priorities at one place.
Rationality of energy efficiency improvement targets under the PAT scheme in India – A case of thermal power plants
Energy Economics

International experience suggests that effectiveness of such schemes is greatly influenced by the assigned targets of the obligated units. Setting rational targets is thus, a key aspect of successful implementation of the scheme. In the present study, we examine the rationality of the targets set for the power sector of India, based on comparing it with energy saving potential of the plants, and the targets assigned to the respective plants. Data envelopment analysis models are used to determine relative efficiency and energy saving potential. The study results indicate that in most cases, (i) The targets are much less than the actual potentials of the thermal power sector, (ii) There exist substantial inefficiencies within the system in both energy use and managerial dexterity; and (iii) If the sector realizes its full potential, then the Energy Saving Certificate market may witness a surplus of 4.7 million certificates on account of thermal power sector alone.
