Cost-allocation problems for fuzzy agents in a fixed-tree network.

Publication Type: Academic Journal

Source(s): Fuzzy Optimization & Decision Making. Dec2022, Vol. 21 Issue 4, p531-551. 21p.

Abstract: Cost-allocation problems in a fixed network are concerned with distributing the costs for use by a group of clients who cooperate in order to reduce such costs. We work only with tree networks and we assume that a minimum cost spanning tree network has...

光网络哑资源深度学习智能管理系统.

Publication Type: Academic Journal

Source(s): Telecommunication Engineering. 2022, Vol. 62 Issue 10, p1433-1437. 5p.

Abstract: 现阶段光网络哑资源的管理多采用人工方式进行监控管理,而引入电子标签的智能光分配 网络(Optical Distribution Network,ODN) 因成本高、改造实施困难导致运营商无法有效提高ODN 网 络质量。通过引入二维码标签及标签分别对分光器及尾纤进行标识,利用深度学习技术,采用 Faster-RCNN 网络对哑资源中尾纤、尾纤标签、分光器、二维码等信息进行统一识别管理,mAP(Mean Average Precision)达82. 96%,满足实际需求,实现了哑资源智能管理,降低了管理...

Empirical risk assessment of maintenance costs under full-service contracts.

Publication Type: Academic Journal

Source(s): European Journal of Operational Research. Jan2023, Vol. 304 Issue 2, p476-493. 18p.

Abstract: • We propose a framework to assess the risk of full-service maintenance contracts. • Our models quantify the impact of machine characteristics on the contract costs. • We build a differentiated, break-even tariff plan for the contract portfolio. • We a...

Collaborative Control for Half-Centralized Open-End Winding Permanent-Magnet Linear Motor Drive Systems.

Publication Type: Academic Journal

Source(s): IEEE Transactions on Power Electronics. Sep2022, Vol. 37 Issue 9, p10399-10411. 13p.

Abstract: Inthis article, a half-centralized open-winding primary permanent-magnet linear motor (HCOW-PPMLM) drives system is proposed, in which two independent voltage-source-inverters (VSIs) and one common VSI are required to supply two open-winding movers. Co...

Optimizations of Managerial Maintenance Policies.

Publication Type: Academic Journal

Source(s): International Journal of Reliability, Quality & Safety Engineering. Aug2022, Vol. 29 Issue 4, p1-13. 13p.

Abstract: This paper takes up managerial maintenance policies during different phases for mission executions. When a mission execution is divided into two phases and three phases respectively, replacement, minimal repair and keeping failure status become alterna...

Don't Pass Deferred Maintenance Costs to the Next Generation! The Effects of Politics on State Highway Maintenance Spending.

Publication Type: Academic Journal

Source(s): Public Works Management & Policy. Apr2022, Vol. 27 Issue 2, p127-151. 25p.

Authors:

Abstract: Routine maintenance spending for public infrastructure is critical for reducing life-cycle costs, and improving asset preservation and quality. Yet, states focus more on building new roads and expansion than maintaining existing assets' conditions. Def...

Age replacement policy in the case of no data: the effect of Weibull parameter estimation.

Publication Type: Academic Journal

Source(s): International Journal of Production Research. Oct2020, Vol. 58 Issue 19, p5851-5869. 19p. 2 Charts, 11 Graphs.

Abstract: Age replacement is a common maintenance policy when wear-out failures occur, and it is characterised by periodic replacement of components. Data on time to failure (TTF), often modelled with the Weibull function, are necessary for estimating optimal re...

Modified quality loss for the analysis of product quality characteristics considering maintenance cost.

Publication Type: Academic Journal

Source(s): Quality Technology & Quantitative Management. May2022, Vol. 19 Issue 3, p341-361. 21p.

Abstract: In view of the fact that the product cannot be restored to new for the actual maintenance, and the degradation rate gradually increases after the maintenance. A concept, quality characteristics of products should obey a multi-stage linear variation dur...

On the optimization of maintenance storage cost in industry a fuzzy logic application.

Publication Type: Academic Journal

Source(s): International Journal of Quality & Reliability Management. 2022, Vol. 39 Issue 4, p1020-1039. 20p.

Abstract: Purpose: The purpose of this paper is to construct a fuzzy logic model that acts as a decision support system to minimize inventory-related costs in the field of industrial maintenance. Achieving a balance between the unavailability and over-storage of...
