People in complex scenarios face the challenge of understanding the purpose and effect of other human and computational behaviour on their own goals through intent recognition. They are left asking what caused person or system ‘x’ to do that? The necessity to provide this support human-computer interaction has increased alongside the deployment of autonomous systems that are to some degree unsu...

In this paper, we describe a system that reacts to both possible system breakdowns and low user engagement with a set of conversational strategies. These general strategies reduce the number of inappropriate responses and produce better user engagement. We also found that a system that reacts to both possible system breakdowns and low user engagement is rated by both experts and non-experts as ...

The paper deals with a stochastic multi-product sequencing and lot-sizing problem for a line that produces items in lots. Two types of uncertainties are considered: random lead time induced by machine breakdowns and random yield to take into account part rejects. In addition, sequence dependent setup times are also included. This study focuses on maximizing the probability of producing a requir...

This paper presents Dialogos, a real-time system for human-machine spoken dialogue on the telephone in task-oriented domains. The system has been tested in a large trial with inexperienced users and it has proved robust enough to allow spontaneous interactions both to users which get good recognition performance and to the ones which get lower scores. The robust behavior of the system has been ...

The problem of finding robust solutions for scheduling problems is of utmost importance for realworld applications as they operate in dynamic environments. In such environments it is often necessary to reschedule the existing plan due to various failures (e.g., machine breakdowns, sickness of employees, etc). Thus a robust solution (i.e., a quality solution which can be modified easily accordin...

This paper evaluates the tardiness performance of a complex dynamic manufacturing environment. These sampling-based adaptive heuristic in a dynamic manufacturing­ 'changes' include machine breakdowns, unavailability of environment. A test bed, following a real world manufacturing material and other resources to perform manufacturing system, has been developed. The proposed algorithm has been op...

Alzheimer’s disease (AD) is an increasingly prevalent cognitive disorder in which memory, language, and executive function deteriorate, usually in that order. There is a growing need to support individuals with AD and other forms of dementia in their daily lives, and our goal is to do so through speech-based interaction. Given that 33% of conversations with people with middle-stage AD involve a...

On-line vibration monitoring of Rotary Machines is a fundamental axis of development and industrial research. Its purpose is to provide knowledge about the working condition of machines at each moment without stopping the production line. This method allows avoiding the production losses related to breakdowns and reducing overall maintenance costs. Bearing fault diagnosis is important in vibrat...

Unplanned disruptive events and disturbances such as arrivals of rush orders or machine breakdowns must be managed locally to avoid propagating the effects along the value chain. To overcome the traditional separation between task scheduling and manufacturing execution systems the novel idea of emergent synthesis/control of schedules for better handling the dynamics at the shop-floor is propose...
