A modelling language for assembly sequences representation, scheduling and analyses

Abstract

International audienceThe aim of this paper is the study of methods for assembly representation supporting the level of automation (LoA) decision .process. Based on a literature review on the topic of LoA deciding, a need for involving the assembly sequence in the decision was identified. The representation methods used in both assembly modeling and planning and other more generic approaches in the literature were studied and evaluated. The evaluation has been based on a requirements definition describing how the representation should support the decision about automation. Identified gaps in requirement satisfaction from the existing approaches led to the definition of the Assembly Sequence Modeling Language (ASML), a new modeling language that combines principles from and improvements on the studied methods and a standard vocabulary of assembly actions. The modeling language was demonstrated in an assembly example and was successfully evaluated with regard to the defined requirements. Thus, this new modeling approach, ASML, is offered as an innovative and intuitive support in the decision making process for selecting automation levels in Assembly

A review of cost estimation models for determining assembly automation level

“…Yet, it does not include processes architectures, particularly parallelisms or choice subsequences, between resources, or within same resources. More dedicated modeling languages, such as ASML (Salmi, David, Summers, & Blanco, 2014) using a standardized vocabulary of operations representation, or SoP (Bengtsson et al, 2012) may be more appropriate. Using ASML for example can help to ensure the standardization of the approach (row F7 of Table 3) thanks to its standardized vocabulary, rules (Salmi et al, 2014), and time estimation techniques (Salmi et al, 2015a).…”

Other vocabularies for modeling operations and time estimating, particularly for assembly, can be found in Maynard and Stegemerten (1948) or Boothroyd et al (2011).…”

An Organizational Perspective of Human Resource Modeling

“…In [39] we identify three different production process modeling approaches and languages: (i) traditional ways to specify production processes, like Bill of Materials and Operations (BOMO) [15], and Failure Mode and Effects Analysis (FMEA) [36]; (ii) GPMLs with their extensions that can be used for production process modeling, like Business Process Model and Notation (BPMN) [17,27], UML activity diagrams [28], and Subjectoriented Business Process Management (S-BPM) [26]; and (iii) process modeling languages custom made to support production process or production system modeling, like Manufacturing Execution System Modeling Language (MES-ML) [33], and Assembly Sequence Modeling Language (ASML) [42]. These languages are aimed at modeling different aspects of production processes.…”
