This paper positions and justifies an ongoing research project, the doctoral research of the first-named author. Two of the authors have previously critically reviewed the literature concerning the relationships between data, information and knowledge (Gregory & Descubes 2011a). This paper introduces personal information management systems PIMS as a mechanism used to support the personal knowle...

I t is increasingly common for seismic surveys to take place among busy and complex operating fields. The variety and intricacy of simultaneous operations (SIMOPS) considerations have increased dramatically as oilfields and their infrastructure have developed. The implications of these disruptions range from unnecessary delays and downtime to a compromising of data quality. These effects are bo...

background: taking visual acuity is an important part of an eye routine examination. this study was conducted to compare visual acuity measured using an iranian digital tumbling e chart with visual acuity measured using an italian digital tumbling e chart as a familiar foreign chart. materials and methods: this study was carried out on 200 participants (400 eyes; healthy n=40, glaucoma n=40, re...

multivariate control charts such as hotelling`s t^ 2 and x^ 2 are commonly used for monitoring several related quality characteristics. these control charts use correlation structure that exists between quality characteristics in an attempt to improve monitoring. the purpose of this article is to discuss some issues related to the g chart proposed by levinson et al. [9] for detecting shifts in ...

The n×m minimum-makespan general job-shop scheduling problem, hereafter referred to as the JSSP, can be described by a set of n jobs {Ji}1≤j≤n which is to be processed on a set of m machines {Mr}1≤r≤m. Each job has a technological sequence of machines to be processed. The processing of job Jj on machine Mr is called the operation Ojr. Operation Ojr requires the exclusive use of Mr for an uninte...

A basic function of Process-aware Information Systems (PAISs) is to offer work to resources. The elementary pieces of work are called work items, e.g. “Approve travel request XYZ1234”. Work items are offered to users via so-called work-list handlers, which take care of work distribution and authorisation issues. Typically, PAISs use a so-called “pull mechanism”, i.e. work is offered to all reso...

The paper describes the possibility of using of the Preactor Express software as a visualisation and manipulation platform for custom scheduling algorithms. The implementation of a custom scheduling algorithm for a real-world application is often far less time consuming than developing a practical and comfortable user interface for the application. It is the reason why many of scheduling algori...

Unplanned disruptive events and disturbances such as arrivals of rush orders or machine breakdowns must be managed locally to avoid propagating the effects along the value chain. To overcome the traditional separation between task scheduling and manufacturing execution systems the novel idea of emergent synthesis/control of schedules for better handling the dynamics at the shop-floor is propose...

ity coordination expert system (RACES) to solve aircraft-parking problems. RACES includes a knowledge-based scheduling system that assigns all daily arriving and departing flights to the gates and remote spots with domain-specific knowledge and heuristics acquired from human experts. RACES processes complex scheduling problems such as dynamic interrelations among the characteristics of remote s...

The Oz Explorer [Sch97] is a visual constraint programming tool for Oz. Oz is a concurrent constraint language providing for functional, object-oriented, and constraint programming [Smo95]. It has a simple yet powerful computation model which extends the concurrent constraint model by first-class procedures, concurrent state and encapsulated search. The Explorer uses the search tree of a constr...
