r-FrMS: a relation-driven fractal organisation for distributed manufacturing systems

Abstract

Up-to-date market dynamics and decentralisation have brought about the need of flexible and robust organisational structures for manufacturing resources. To meet the need of such an environment, the manufacturing system should be equipped with an open, reconfigurable and scalable organisational structure. This paper proposes a novel organisational model, referred to as a relation-driven fractal organisation, to meet the requirements. The proposed model applies the concept of a fractal to its organisational structure and adopts a relational pattern between composing entities as a basic building block for organising. In this paper, the existing fractal-like systems involved in manufacturing systems are investigated, and the fractal organisation is derived as their super-ordinate concept. Then, r-FrMS, a relation-driven fractal organisation applied into distributed manufacturing systems, is proposed along with its organising mechanism which adopts employment relations between manufacturing resources as its organising principle.

Agent-based hierarchical production planning and scheduling in make-to-order manufacturing system

“…Based on the original concept of FrMS, (Shin et al, 2009b,a) developed a lq Relation-driven Fractal Manufacturing System'(rFrMS) to help MTO manufacturing systems hierarchically plan and schedule customer orders. In r-FrMS, manufacturing resources are modelled as Autonomous and Intelligent Resource (AIR) units (i.e., fractals) which are organised hierarchically through the employer-employee relationships.…”

Characteristics of redistributed manufacturing systems: a comparative study of emerging industry supply networks

“…Over recent decades, market dynamics have brought about the need for more flexible, reconfigurable and scalable organisational structures to support increasingly dispersed manufacturing resources (Shin et al, 2009;. In turn, supply networks have become increasingly 'disaggregated', with activities spread across multiple firms and locations, with individual manufacturing sites increasingly geographically distributed Christodoulou, 2014, Srai et al 2016).…”
