An Alternative Solution to the Observation Pattern Problem
نویسندگان
چکیده
We have used Fowler's Observation pattern (published in [Fowler 97a]) in a project involving the maintenance of medical records of patients. The pattern has been modi ed to suit the project's particular requirements. We end up with a substantially modied model which could be regarded as an alternative solution. In this paper, we present that alternative model and the underlying rationale. We also suggest, as a separate issue, how the study of analysis patterns can be improved by using a suitable `minimal' application, an application just big enough to cover the pattern in question.

Refueling problem of alternative fuel vehicles under intuitionistic fuzzy refueling waiting times: a fuzzy approach
Using alternative fuel vehicles is one of the ways to reduce the consumption of fossil fuels which have many negative environmental effects. An alternative fuel vehicle needs special planning for its refueling operations because of some reasons, e.g. limited number of refueling stations, uncertain refueling queue times in the stations, variable alternative fuel prices among the stations, etc. I...
متن کاملScheduling a constellation of agile earth observation satellites with preemption
In this paper, we consider a scheduling problem for a set of agile Earth observation satellites for scanning different parts of the Earth’s surface. We assume that preemption is allowed to prevent repetitive images and develop four different preemption policies. Scheduling is done for the imaging time window and transmission time domain to the Earth stations as well. The value of each picture ...
متن کاملA Heuristic Approach for Solving LIP with the Optional Feasible or Infeasible Initial Solution Points
An interactive heuristic approach can offer a practical solution to the problem of linear integer programming (LIP) by combining an optimization technique with the Decision Maker’s (DM) judgment and technical supervision. This is made possible using the concept of bicriterion linear programming (BLP) problem in an integer environment. This model proposes two bicriterion linear programs for iden...
متن کاملA note on "An interval type-2 fuzzy extension of the TOPSIS method using alpha cuts"
The technique for order of preference by similarity to ideal solution (TOPSIS) is a method based on the ideal solutions in which the most desirable alternative should have the shortest distance from positive ideal solution and the longest distance from negative ideal solution. Depending on type of evaluations or method of ranking, different approaches have been proposing to calculate distances ...
متن کاملSolving the inverse problem of determining an unknown control parameter in a semilinear parabolic equation
The inverse problem of identifying an unknown source control param- eter in a semilinear parabolic equation under an integral overdetermina- tion condition is considered. The series pattern solution of the proposed problem is obtained by using the weighted homotopy analysis method (WHAM). A description of the method for solving the problem and nding the unknown parameter is derived. Finally, tw...
