Measuring the performance of a production system has been an important task in management for purposes of control, planning, etc. Lord Kelvin said :“When you can measure what you are speaking about, and express it in numbers, you know something about it; but when you cannot measure it, when you cannot express it in numbers, your knowledge is of a meager and unsatisfactory kind.” Hence, manag...

obtaining these measures. P otential computer system users or buyers usually employ a computer performance evaluation technique only if they believe its results provide valuable information. System Performance Evaluation Cooperative (SPEC) measures are perceived to provide such information and are therefore the ones most commonly used. SPEC measures are designed to evaluate the performance of e...

The purpose of much computer science research is to invent algorithms, and generate evidence to convince others that the new methods are worthwhile. All too often, however, the work has no impact, because the supporting evidence does not meet basic standards of rigor or persuasiveness. Here the notion of “experiment” is explored, with reference to our current investigation into distributed text...

There is a problem with blood pressure control in the United States--a problem with significant implications for the health and welfare of the populace. This problem is bigger than managed care, but managed care organizations have both unique opportunities and unique obligations to address it. NCQA has responded to this problem, and to the opportunity for better care implicit in it, by introduc...

Measuring transportation performance has become at once more urgent and complicated. Pressures of ITS deployment and accountability contribute to the urgency. Demands for comprehensive measures create complexity. This note proposes a simple performance system, named TransAcct. Its virtues are: attention to the most important measures, use of readily available sensor measurements and processing ...

The decision theory is defined typically as the combination of utility theory and probability theory. In this paper we generalize the decision theory as the performance measure theory and uncertainty theory. Intelligent agents look for approximate optimal decisions under bounded resources and uncertainty. The $-calculus process algebra for problem solving applies the cost performance measures t...

Xavier de Montgros, Supply Chain Development Director at Hewlett-Packard (HP), was referring to HP’s Inventory-Driven Cost (IDC) metric, introduced in the late 1990s in an attempt to restore the company’s profitability in the highly competitive personal computer (PC) industry. The new performance measure was intended to focus the organization’s attention on creating value in the supply chain th...

This paper studies the incentive effects of a balanced scorecard within a multitask agency framework under both formal and relational contracts. First, the main characteristics of the balanced scorecard are analyzed with respect to performance measure congruity. It is shown that under complete verifiability, a properly designed balanced scorecard is capable of perfectly aligning the interests o...

this paper deals with the problem of optimizing two-stage structure decision making units (dmus) where the activity and the performance of two-stage dmu in one period effect on its efficiency in the next period. to evaluate such systems the effect of activities in one period on ones in the next term must be considered. to do so, we propose a dynamic dea approach to measure the performance of su...

This study evaluated the responsiveness of the Canadian Occupational Performance Measure (COPM), an individualized, client-centered outcome measure for the identification and evaluation of self-perceived occupational performance problems. We recruited 152 consecutive patients with various diagnoses, admitted to the outpatient clinic of two occupational therapy departments, to complete a COPM in...
