Technological advances, financial possibilities and changes of demands have increasingly affected the pavement maintenance environment for outsourcing in recent years. This induces complexity in the contracting methods of pavement maintenance activities. Despite the fact that current contracting practices on pavement maintenance activities are not sufficient to deal with changes providing the i...

funding decision is one of the financial strategic decisions of a corporation. there are also two other finan-cial strategic decisions that a corporation faces, the investment and the dividend decision. this paper de-scribes briefly the investment and the dividend decision, although its main focus is on funding decision. in de-scribing the funding decision the researchers will first explain the...

This paper integrates noncyclical preventive maintenance with tactical production planning in multistate systems. The maintenance policy suggests noncyclical preventive replacements of components, and minimal repair on failed components. The model gives simultaneously the appropriate instants for preventive maintenance, and production planning decisions. It determines an integrated lot-sizing a...

Base registries are trusted authentic information sources controlled by an appointed public administration or organization appointed by the government. Maintaining a base registry comes with extra maintenance costs to create the dataset and keep it up to date. In this paper, we study the possibility to entangle the maintenance of base registries at the core of existing administrative processes ...

BACKGROUND Infliximab is an effective therapy for inflammatory bowel disease (IBD). However, more than 50% of patients lose response. Empiric dose intensification is not effective for all patients because not all patients have objective disease activity or subtherapeutic drug level. The aim was to determine how an objective marker of disease activity or therapeutic drug monitoring affects clini...

The subject of this paper is determining optimal replacement decisions for components under stochastic deterioration. Using the discrete renewal theorem, three cost-based criteria for comparing maintenance decisions over unbounded horizons are determined in Sec. 2: (i) the average costs per unit time, (ii) the discounted costs over an unbounded horizon, and (iii) the equivalent average costs pe...

This article surveys the application of gamma processes in maintenance. Since the introduction of the gamma process in the area of reliability in 1975, it has been increasingly used to model stochastic deterioration for optimising maintenance. Because gamma processes are well suited for modelling the temporal variability of deterioration, they have proven to be useful in determining optimal ins...

Much of the emphasis in identifying a software maintenance project’s technical debt involves analysis of the code to be maintained. Our recent analysis of the sources of software maintenance cost have identified the major sources of technical debt for non-developer maintenance organizations to originate from non-technical acquisition and development decisions and practices. As a way of identify...

This paper deals with the condition-based maintenance of single-unit systems which are subject to the competing and dependent failures due deterioration and traumatic shock events. The main aim is to provide a model to assess the value of condition monitoring information for the maintenance decision-making. A condition-based periodic inspection/replacement policy is developed and compared with ...
