This paper proposes a novel method of scheduling parallel execution of planning and action for a visionmotion planning problem. A planning process can be viewed as a process of gradually reducing the plan candidates towards the final commitment to one plan. Using criteria on deciding if an action sequence is consistent with the remaining plan candidates (consistency criterion), and on when to c...

We describe a framework for planning in dynamic environments. A central question is how to focus the sensing performed by such a system, so that it responds appropriately to relevant changes, but does not attempt to monitor all the changes that could possibly occur in the world. To achieve the required balance, we introduce rationale-based monitors, which represent the features of the world sta...

The dominant view of design in information systems and software engineering, the Rational Model, views design and engineering as a methodical, plan-centered, approximately rational process of optimizing a design candidate for known constraints and objectives. It persists despite extensive empirical evidence that it does not reflect design practice and no evidence that attempts to adopt rational...

While software process improvement is well established as a practice, it still presents challenges for some adopters. Drop-outs from SPI programs are not uncommon. The paper argues that SPI sustainment is a function of the organizational context of the program, not just of the program (or SPI ‘product’) itself. Critical in this context is the organization’s operational capabilities and capacity...

Due to the rapid changes in circumstances of cooperates such as globalization, technical innovation and competition, inter-dependence among cooperates which compose supply chain has been intensified. This make cooperates be exposed to various risk and even a small uncertainty can disrupt the balance of whole supply chain. Therefore, in this paper, the framework to develop alternative backorder ...

The optimisation process of scheduling an incremental/iterative software project can be approached as a multi criteria decision problem, formulated by a linear programming model, aimed to propose alternative project schedules and examine cost trade-offs. In this paper, we apply the prominent economic theory of Real Options to analyse project investment risks and discover the economic value asso...

I-X is a research programme intended to create a well-founded approach to allow humans and computer systems to cooperate in the creation or modification of some product such as a design, physical entity or plan – i.e. it supports mixedinitiative synthesis tasks. The I-X mixed-initiative approach involves the use of shared models for task-orientated communication between human and computer agent...
