The (minimizing) achievement function of the traditional goalprogramming (GP) model has five basic forms: n(i), p(i), (n(i)+p(i)), (n(i)-p(i)), and (p(i)-n(i)), where n(i) and p(i) are nonnegative under and over achievement variables in the i(th) goal-constraint. Zhang and Shang (2001) proposed the theory of Coal Programs with -n(i), -p(i), and -(n(i)+p(i)) goals, which has many interesting and practical applications. This paper extends the theory further into the nonlinear situation and proposes a new algorithm for solving the ensuing nonconvex nonlinear program. Results obtained in this paper shows that the basic conclusions for the linear GP model still hold for the nonlinear case.

Traditional formulations on reliability optimization problems have assumed that the coefficients of models are known as fixed quantities and reliability design problem is treated as deterministic optimization problems. Because that the optimal design of system reliability is resolved in the same stage of overall system design, model coefficients are highly uncertainty and imprecision during design phase and it is usually very difficult to determine the precise values for them. However, these coefficients can be roughly given as the intervals of confidence. In this paper, we formulated reliability optimization problem as nonlinear goal programming with interval coefficients and develop a genetic algorithm to solve it. The key point is how to evaluate each solution with interval data. We give a new definition on deviation variables which take interval relation into account. Numerical example is given to demonstrate the efficiency of the proposed approach. (C) 1997 Elsevier Science Ltd.

The (minimizing) achievement function of the traditional goalprogramming (GP) model has five basic forms: ni,pi,(ni+pi),(n-pi),and (pi-ni),where ni and pi are nonnegative under and over achievement variables in the ith goal-constraint. Zhang and Shang (2001) proposed the theory of goal Programs with -ni,-pi and -(ni+pi) goals, which has many interesting and practical applications. This paper extends the theory further into the nonlinear situation and proposes a new algorithm for solving the ensuing nonconvex nonlinear program. Results obtained in this paper shows that the basic conclusions for the linear GP model still hold for the nonlinear case.

Three methods were developed to solve nonlinear goal programming (NLGP) problems by adapting and extending the Nelder-Mead method, the Complex search method, and the Hooke and Jeeves Pattern Search method to account for multiple criteria. These modifications were largely accomplished by using goalprogramming, lexicographic ordering, and partitioning concepts. The three resulting methods were the Lexicographic Nelder-Mead (LNM) method, the Partitioning Nelder-Mead-Complex (PNMC) method, and the Partitioning Pattern Search (PPS) method. Each method is analyzed based on results and compared with the other methods. Each of the methods appears to function effectively and generate a good solution. In general the PPS method did well in respect to computational time and number of iterations, however, none of the methods clearly outperformed or was outperformed by the other methods.

In this study, the authors proposed a solution for directly using genetic algorithms without linear conversion for solving nonlinear goal programming problems involving interval coefficients. The proposed technique involves directly computing left-side interval numbers in the goal constraint equation from the genetic algorithm solution and comparing their size with those of the right-side numbers, for obtaining new difference variables. These difference variables vary depending on the goal type;they are defined using weights which express interval order evaluation criteria. In addition, as an example of application field for this method, the authors studied a large-scale problem for optimal design of system reliability involving interval coefficients, in order to clarify localization of this method.

This study proposes a combined 'nonlineargoal-programming'-based 'differential evolution' (DE) and 'artificial neural networks' (ANN) methodology for grade optimization in iron mining production processes. The nonlineargoal-programming model has decision variables of 'cutoff grade,' 'dressing grade' and 'concentrate grade,' with the goals being 'concentrate output,' 'resource utilization rate' and 'economic benefit (profit).' The model, which contains three unknown functions, the 'loss rate,' the 'ore-dressing metal recovery rate' and the 'total cost,' is subsequently converted into an unconstrained optimization problem, to be solved by our integrated DE-ANN approach. DE is used to search for the optimum combination of the cutoff, dressing and concentrate grades, with the crossover rate in the DE analysis being dynamically adjusted within the evolutionary process. The loss rate is calculated by a regression model, whilst the ore-dressing metal recovery rate and the total cost functions are, respectively, calculated using 'back-propagation' and 'radial basis function' neural networks. We subsequently go on to analyze a case study of the Daye iron mine in China to demonstrate the reliability and efficiency of our proposed approach. Our study provides a novel approach for decision makers to guide production and management in iron mining.

In this paper, we cast the problem of income redistribution in two different ways, one as a nonlinear goal programming model and the other as a game theoretic model. These two approaches give characterizations for the probabilistic approach suggested by Intriligator for this problem. All three approaches reinforce the linear income redistribution plan as a desirable mechanism of income redistribution.

In some cases, decision makers (DMs) need to use multiplicative linguistic terms to express evaluations, and probabilistic linguistic preference relation (PLPR) cannot meet the needs of decision makers. Multiplicative probabilistic linguistic preference relations (MPLPRs) can solve this problem. The consistency of preference relations is crucial to ensure reliable decision results. We define the ordinal consistency of MPLPRs, and improve the ordinal consistency of MPLPRs. In order to facilitate calculation, the mapping from probabilistic linguistic term set (PLTS) to linguistic term is defined. In probabilistic linguistic information decision-making methods, some methods only collect the information of the decision matrix, and some methods only collect the information of the preference matrix, and almost no decision method that uses the decision matrix and the preference relation information at the same time, but the optimal ranking of alternatives is obtained according to the comprehensive attribute of alternatives. Based on the above considerations, first, we construct a nonlinear objective optimization model containing alternative attributes and alternative preferences. Then, a probabilistic linguistic group decision-making method based on attribute decision and multiplicative preference relations is further proposed. Finally, the feasibility of the method is illustrated by an example of hospital evaluation, and the advantages of the proposed method are verified by comparing the differences between the proposed method and other methods.
