A multi-attribute utility model for dispute resolution strategy selection

Disputes are inevitable in construction projects. Skills in dispute resolution should be part of the toolkit of any practitioner in a managerial position. Dispute resolution procedures such as litigation, arbitration, mediation, dispute adviser and negotiation are widely practised. However, frequently the question is how to systematically determine which dispute resolution strategy to adopt given the nature of disputes. Even though the topic of dispute resolution has been widely discussed and heavily researched, few studies have been conducted with respect to this question. A decision-making model has been developed using the analytical hierarchy process (AHP) and multi-attribute utility technique (MAUT). The model comprises four parts: selection criteria, dispute resolution strategies, collection of utility factors and selection criteria weightings. These were developed from empirical data collected through an interview survey with selected experts in the field. The model is designed to identify in a systematic manner an appropriate dispute resolution strategy for a given dispute, rather than relying on subjective decisions. The model is tested using a hypothetical scenario in which three case studies are evaluated.

广域电磁法近区高分辨率的研究

广域电磁法与其他人工场源电磁法相比较,其显著特点是近区分辨率反常的低于远区分辨率。本文对此进行了研究,是由于其感应测深的幅值受几何测深幅值控制所致。本文进一步对广域电磁法近区高分辨率的探讨,研究了近区电场虚分量多项式的作用,发现电场虚分量第三项具有高分辨率因子的存在。据此,推导出广域电磁法近区高分辨率的解析表达式。本文的结果,可使广域电磁法无需广域探测,只需在近区探测,不仅施工方便、合理和信噪比高,而且能比远区和过渡区获得更大的探测深度,更精细的分层能力,以此更灵敏发现良导金属矿体。

Survey of construction lawyers' attitudes and practice in the use of ADR in contractors' disputes

Continuing a survey of contractors' perceptions about alternative dispute resolution (ADR) this paper seeks to report an investigation of the level of involvement of legal advisors to the construction industry in the dispute resolution process and the perceptions that legal professionals have about the use of ADR in construction disputes. The research findings are that contractors are likely to involve lawyers in the dispute resolution procedure, particularly when disputes concern a legal issue, when the parties to the dispute are entrenched in their argument, or when the other party insists on using legal professional assistance. In these defined circumstances, legal advisors will be influential in determining the potential use of ADR. The paper concludes that lawyers are unlikely to recommend ADR for most disputes between contractors, particularly if the dispute resolution process is perceived to involve the use of delay by main contractors, if the parties are fixed in their arguments or if they are exhibiting adversarial behaviour in their approach to the dispute. In these circumstances lawyers and their clients prefer the force of the formal systems over conciliatory ADR procedures.

The appropriate spatial resolution of future weather files for building simulation

Building thermal modelling packages require weather data to predict representative internal conditions. Typically, around the world, reference weather years of various forms are used which are created from observations at aparticular location. However, it is unlikely that this location is identical to that of the building. This can lead toweather files for coastal locations being applied to inland and upland sites or vice versa. In the UK, the UKCP09 weather generator has the ability to produce weather at a 5 km resolution. Currently, it is unclear how useful this extra spatial resolution will be and it is this question that is addressed here. It is found that for both future and present climate, the spatial variability of the weather is the dominating factor. Although there are geographies where a low spatial resolution can be used, there are regions where a much higher resolution is necessary.
