This paper presents a novel method to solve non-linear time-cost tradeoff (TCT) problem of real world engineering projects. Multiobjective genetic algorithm (MOGA) is employed to search for optimal TCT profile. Applicability of ANN based model for rapid estimation of time-cost relationship by invoking its function approximation capability is investigated. ANN models are then integrated with MOG...

One of the primary outcomes of a software process assessment is visibility of the capability of a software process which among other things, informs us of the ability of a process to deliver consistent product quality levels. In safety critical domains, such as the medical device sector, high product quality – and particularly high product safety is an important consideration. To address this s...

The classical method of process capability analysis necessarily assumes that collected data are independent; nonetheless, some processes such as biological and chemical processes are autocorrelated and violate the independency assumption. Many processes exhibit a certain degree of correlation and can be treated by autoregressive models, among which the autoregressive model of order one (AR (1))...

Acceptance sampling plan is a method to make decision on either accepting or rejecting a specific lot or more generally to inspect the quality of products that can be used by different methods. Along with this, one suitable measure to improve manufacturing processes is to analyze process capability indices. These indices have many applications in production environments. In this paper, a repeti...

It is a challenge for small and very small organizations to adopt software process improvement models and the associated assessment methods to improve their software process. A number of customized assessment methods based on SPI models, such as CMM/CMMI and ISO 15504, have been proposed to fit the needs of such organizations. To help them select an assessment method relevant to their needs, th...

It is difficult to improve software quality by relying on conformance to industry standards by continuously upgrading from one standard or model to another standard or model because this exercise is complicated for some software organizations. ‘Many multinational companies, developed internal standards based on the military standards, and then sought to improve the standard even further as thei...

In this column, I use a common situation facing many requirements engineers to illustrate that " one size does not fit all " when it comes to selecting a project-specific requirements engineering process. I then recommend a metaprocess for constructing such a process based on the use of a preexisting process framework and its associated repository of reusable process components. I conclude the ...

This research addresses issues relating to the implementation of software process improvement (SPI) initiatives. A number of advances have been made in the development of software process improvement (SPI) standards and models, e.g. Capability Maturity Model (CMM), more recently CMMI, and ISO's SPICE. However, these advances have not been matched by equal advances in the adoption of these stand...

Requirements management measures help organizations to understand, control and assess requirements management process. This paper validates empirically a set of requirements management measures. The measures were defined for the five specific practices of requirement’s management key process area in capability maturity model integration by applying the goal question metrics paradigm to the five...
