- AbstractThe emphasis of this exploratory paper is on some maintenance related accidents occurred during previous decades and the aim is to develop a model for preventing such accidents by understanding the major causes and the influencing factors among them. The model is intended to explain the affecting factors in a fatal accident and how they are related to one another. To fulfil the aim of study, a Bayesian network model was developed using the GeNIe 2.0 software and further on the relations between different factors were assigned. The model was developed based on a case study of Tosco Avon refinery accident in Martinez, California occurred on February 23rd, 1999 where four workers were killed in a fiery accident. The proposed model could predict the final result of the execution of a corrective maintenance process to make a safer decision. Since the model was developed based on Tosco Avon refinery accident case, validation has been carried out regarding some other accidents. The results showed that the proposed model is a suitable tool to predict the outcomes of an action in corrective maintenance. In addition the model can be adjusted to different applications.

- This paper explains why CD activities are valuable from a signaling perspective. By signaling, the firm attempts to influence the behavior of a customer. However, as most signals can be imitated or faked by competitors, a signal will only be effective from the firm‘s perspective if it is perceived as reliable by customers, which requires the signal to be costly or hard to imitate. This paper explains why repeated customer interaction during the CD phase can create new or significantly improved capabilities on the one hand, and create lead users on the other hand. The creation of new capabilities and lead users are two sources of Hard to Imitate Signals (HIS) which are perceived as reliable by customers and thus contribute to innovation and market diffusion. The paper discusses some general implications of the signaling perspective for CD.
