“…These findings are consistent with literature that draws attention to the importance of workforce and skills (Bennour and Crestani, 2007; Fraser et al , 2007; Gaimon, 2008). These findings are also consistent with past cases of companies and industries that found it necessary to cut back on automation and re‐introduce human operatives in order to develop quality, improve productivity, and increase profitability (Agrawal et al , 2001; Davenport and Prusak, 2000; The Economist , 1995).…”

PurposeThere are guidelines for information and communication technology (ICT) applications which are already established in manufacturing. These guidelines include recommendations such as: alignment of ICT applications with strategy, involvement of the full range of stakeholders, and careful planning and monitoring. A recommendation from outside of manufacturing is that information and communication design should be carried out in conjunction with ICT applications. The purpose of the research reported in this paper is to investigate the relevance of information and communication design to applications of advanced ICTs used in the instruction of manual skills.Design/methodology/approachLiterature review, interviews, and five quasi‐experimental studies are used.FindingsThe design of information and its communication is relevant to the instruction of manual skills with ICTs and, in particular, important for instruction with augmented reality (AR).Research limitations/implicationsThere are only 92 participants in the five quasi‐experimental studies.Practical implicationsThis paper provides an overview of information and communication design issues. Examples are provided of how these issues manifest themselves in the application of advanced ICTs, such as virtual reality and AR, which can be used in the instruction of manual skills.Originality/valueThe originality of the research reported in this paper is that it goes beyond further investigation of established guidelines for ICT applications. The value of this paper is that it draws attention to the potential of information and communication design to improve ICTs implementations. It also draws attention to the need for balanced comparisons in the assessment of all ICTs prior to their implementation.

“…Although Bennour and Crestani (2007) formalise a connection between general employees' expertise (eg in the form of know-how) and their performance, however, they do not provide the subsequent long-term observation of this development. Moreover, Baines and Benedettini (2007, p 121) investigated the practicability of a concept that was purely theoretic to date (Baines et al, 2005).…”

Many industrial nations are faced with the question of the effects of the demographic development, particularly with respect to the employment of an ageing workforce. An increase in the share of older employees is to be expected, while the share of younger employees and therefore the number of skilled workers decreases. Their employment will not only be mandatory but will also increase in numbers in order to maintain the share of skilled workers, their know-how, and their experience. However, this development is opposed by the deterioration of physical abilities, which needs to be compensated by technical aids and organisational measures. The associated effects on occupation and productivity may be estimated as to quality but cannot be quantified on an operational level to date. However, special approaches for the modelling of personnel-oriented simulations are available in order to answer these questions for individual production systems with respect to the quantitative assessment. Using the simulator ESPE-AS, which is geared towards age-appropriate structuring of processes and tasks, performance developments of a given workshop and workforce can be forecasted for future time spans. This article describes this procedure and shows with the help of a pilot study how the development of the productivity of an ageing workforce can be forecasted for a period of several years.The long-term performance of a non-automated manufacturing system significantly depends on the available workforce. Thereby, the efficiency of manufacturing processes that is demanded in every respect, increasingly leads to teamwork solutions, for example, in manual assembly systems of serial products. The commonly high division of labour in this area requires of an individual employee high repetition rates of his task. However, the assembly task assigned to one employee often only takes a few minutes. Increasingly shorter processing times are required in the face of continuous cost reduction measures. In the case of interlinked work systems, this leads to shorter cycle times. However, the requirement for shorter cycle times favours the qualification profiles of younger employees who can usually better handle this necessity than older ones. Often, it is common practice to assign tasks independent from individuals and without any specific consideration of an employee's age and longterm development potential. The differences in the employees' performance potentials are at best implicitly considered when tasks are being assigned.Against the background of an increasing duration of vocation and occupation and the possibly limited chances for continual professional development, the heterogeneity of work performance will become more and more noticeable over the years. As a result, industrial work systems will have to prepare themselves for a performance differentiated staff and to consider appropriate organisational and creative measures. When interpreting future work systems, it is therefore necessary to consider the development of human performance ove...

“…This cost may be caused by delaying the execution of other activity instances, employing extra executors, etc. (Hagen and Alonso 2000;Bennour and Crestani 2007;Van Der Aalst, Rosemann, and Dumas 2007), and its value is determined by many factors such as a i 's importance and urgency. A detailed discussion about the overtime cost is beyond the scope of this paper.…”

“…They either allocate activity instances to suitable resources to meet users' temporal or quality of service (QoS) requirements (Bajaj and Agrawal 2004;Menasce and Casalicchio 2004;Jia and Buyya 2006;Sakellariou et al 2007), or schedule multiple process instances to minimise their delayed numbers (Greg, Jacques, and Clarence 2004;Tramontina and Wainer 2005) or overall completion time (Liu et al 2009). Although the process perspective of workflow scheduling is of most significance, applying scheduling techniques in managing executors' personal work lists is also essential because executors are actually the driving force of workflow (Moore 2002;Bennour and Crestani 2007). At present, preliminary work applies scheduling techniques in managing a personal work list using simple dispatching rules (Eder et al 2003;Eder, Eichner, and Pichler 2006;Rui et al 2009), which doesn't address the complexities and uncertainties involved in personal work list management.…”

Applying scheduling techniques to manage activity instances (tasks) in executors' personal work lists is crucial in workflow management systems (WFMSs). To date, most practical scheduling techniques focus on process (control-flow) perspective of WFMSs but do not adequately address issues relating to work lists containing executors' to-do activity instances. Existing simple-dispatching-rule based techniques cannot fully capture the complexity in personal work list management under dynamic workflow environments. Given this motivation, this paper proposes an approach that applies genetic algorithm (GA) to manage activity instances in personal work lists. This approach is applied according to activity instances' probabilities of satisfying deadlines and costs of violating deadlines. The approach can schedule activity instances among multiple executors' personal work lists and recommend to each executor a list of activity instances that can be successfully executed, while minimising the overall deadline violation cost. Using real-world data collected from three manufacturing enterprises, the paper fits the probability distributions of activity instances' key time features such as starting time and execution durations, and then generates simulation experiment data. This paper also studies the setting of GA's parameters to fit the practical manufacturing scenarios. Finally, by comparing with other seven typical workflow scheduling algorithms, the paper evaluates the effectiveness of our algorithm using a large scale simulation experiment.
