Abstract This paper explores the role of formal methods as part of the user-centred design of interactive systems. An iterative process is described, developing prototypes incrementally, proving user-centred requirements while at the same time evaluating the prototypes that are executable forms of the developed models using ‘traditional’ techniques for user evaluation. A formal analysis complements user evaluations. This approach enriches user-centred design that typically focuses understanding on context and producing sketch designs. These sketches are often non-functional (e.g. paper) prototypes. They provide a means of exploring candidate design possibilities using techniques such as cooperative evaluation. This paper describes a further step in the process using formal analysis techniques. The use of formal methods provides a systematic approach to checking plausibility and consistency during early design stages, while at the same time enabling the generation of executable prototypes. The technique is illustrated through an example based on a pill dispenser.

This study examines the influence of board interlocks and former politicians on decisions regarding acquisitions in Spain. Our research suggests that board interlocks to other firms can positively influence operations in terms of acquisition scale. Our findings also show that this relationship is positively moderated by the presence of former politicians. That is, the effects of interlocks on acquisitions are amplified further when there are former politicians on boards, which confirms their role as community influentials. In the case of Spain, and under-regulated industries, this complementary effect is maintained. However, the role played by interlocks seems to be more important than former politicians, which means that board interlocks can replace other formal methods of acquiring information (through former politicians) while attempting acquisitions.

Formal methods for thirty years have promised to be the solution for the safety certification headaches of railway software designers. This chapter looks at the current industrial application of formal methods in the railway domain. After a recall of the dawning of formal methods in this domain, recent trends are presented that focus in particular on formal verification by means of model checking engines, with its potential and limitations. The paper ends with a perspective into the next future, in which formal methods will be expected to pervade in more respects the production of railway software and systems.

Service robots are increasing significantly, as they are playing a key role in our city-life. This paper depicts the system design of a beverage-sale robotic system named BSR. BSR can sale beverage such as Coca Cola, beers and Sprite to the clients automatically, working as a human seller. The robotic system can also play the role of a casher doing cash in and check out. In this paper, the hardware design including the mechanical structure and the electrical system are introduced firstly. Then, the control strategy is proposed. BSR has been exhibited in a science museum in China and it is well welcomed by the audiences.
