TOPSIS Based Approach to Scoring Negotiating Offers in Negotiation Support Systems

In this paper we analyze the possibility of applying the technique for order preferences by similarity to ideal solution (TOPSIS) to building the scoring system for negotiating offers. TOPSIS is a multiple criteria decision making method that is based on measuring distances between alternatives under consideration and two bipolar reference alternatives, a positive and negative ideal. Thus the criteria used for the evaluation of alternatives should be described using strong scales. However, in the negotiation, the issues are very often described qualitatively, which results in ordinal or even nominal variables that must be taken into consideration in offers’ evaluation process. What is more, TOPSIS may be applied to solving the discrete decision problems while the negotiation space may be defined by the means of continuous variables too. In this paper we try to modify the TOPSIS algorithm to make it applicable to negotiation support and, moreover, discuss the following methodological issues: using TOPSIS for a negotiation problem with continuous negotiation space; selecting the distance measure for adequate representation of negotiator’s preferences and measuring distances for qualitative issues. Finally, we propose a simple additional mechanism that allows for building the TOPSIS-based scoring system for negotiating offers and does not involve negotiators in time consuming and tiresome preference elicitation process. This mechanism requires from negotiators to construct examples of offers that represent some categories of quality and then by using a goal programming approach it infers all the parameters required by the TOPSIS algorithm. We also show a simple prototype software tool that applies the TOPSIS modified algorithm and may be used in electronic negotiation support.     

我国城镇基本养老保险个人账户定位剖析

我国基本养老保险个人账户资金规模要适度,由劳动与社会保障部统一管理。为提高职工缴费的积极性,关键在于提高个人账户的收益率,实现有效保值增值。我国基本养老保险个人账户的"空账"实质是以不明晰的债权形式存在。当前所讨论的"做实"个人账户,实质是个人账户资产存在形式的转换。对于历史"空账",不应该立即"做实",而应比较机会成本与效益,逐步"做实"。而对于新缴纳的个人账户资金,则应明晰产权,不能随便挪用,但当统筹基金不足时,可以有偿使用。个人账户待遇以自身平衡为原则。

Effects of considering uncontrollable factors in sales force performance evaluation

Sales managers often make adjustments for factors such as territory difficulty or representative experience when doing performance evaluations. These adjustments may be subjective, they may be simple ratio calculations (e.g., sales divided by territory size), or they may involve complicated regression analyses. This research attempts an explanation of how and why these adjustments influence perceptions of the performance evaluation process, particularly its fairness and usefulness. Data from two surveys are presented. The first is an exploratory survey of sales managers; the second is a fuller survey of salespeople. Results show that making adjustments for territory difficulty increases perceptions of fairness and usefulness of the evaluation system among both sales managers and salespeople. Feedback quality is a key mediator of these effects for both groups. A different pattern exists with regard to accounting for representative experience. For sales managers, there are no effects on feedback quality or fairness or usefulness. Salespeople, however, rate systems that account for representative differences as providing better feedback quality, as more fair, and as more useful. © 2000 John Wiley & Sons, Inc.

Can a positive approach to performance evaluation help accomplish your goals?

Organizations typically depend upon performance evaluation measures to provide feedback to managers regarding the achievement of strategic objectives. However, performance evaluation is often focused on negative aspects of performance, suggesting that managers may not be receiving enough reinforcement of the positive elements of their decisions. When applied effectively, performance measures not only create desirable motivation, but also encourage communication and the exchange of information among managers. Under this scenario, individual managers achieve their personal goals, while the organization satisfies its strategic objectives. The application of positive organizational scholarship principles to performance evaluation metrics can help make the evaluation process more effective. Using performance measures framed in a positive manner can help generate more creativity, more problem-solving ability, and greater communication among managers, leading to progress toward organizational objectives. We illustrate this approach with the application of positive metrics to the balanced scorecard for mid-level managers in implementing business strategy.
