Abstract

Purpose

This paper aims to propose a reliable local search algorithm having steepest descent pivot rule for computationally expensive optimization problems. In particular, an application to the design of Permanent Magnet Synchronous Motor (PMSM) drives is shown.

Design/methodology/approach

A surrogate assisted Hooke‐Jeeves algorithm (SAHJA) is proposed. The SAHJA is a local search algorithm with the structure of the Hooke‐Jeeves algorithm, which employs a local surrogate model dynamically constructed during the exploratory move at each step of the optimization process.

Findings

Several numerical experiments have been designed. These experiments are carried out both on the simulation model (off‐line) and at the actual plant (on‐line). Moreover, the off‐line experiments have been considered in non‐noisy and noisy cases. The numerical results show that use of the SAHJA leads to a saving in terms of computational cost without requiring any extra hardware components.

Originality/value

The surrogate approach in the design of electric drives is novel. In addition, implementation of the proposed surrogate model allows the algorithm not only to reduce computational cost but also to filter noise caused by the sensors and measurement devices.

Abstract

Purpose

This paper aims to present historical examples of collaborations between brand strategists and artists; provide an extensive, structured overview of existing published research on such collaborations and their effects; present seven papers comprising this special issue; and discuss ideas for further research into brand–art collaboration.

Design/methodology/approach

This is an editorial based mainly on an extensive and broad literature review.

Findings

First, this editorial underpins the relevance of brand–art collaboration in the past and present by reference to real examples. Second, it structures the diverse literature into four key aspects of the topic: inspiration, insights, identity and image. Third, it provides a glimpse of the seven papers selected for this special issue. Fourth and finally, it identifies a total of 16 avenues for further research, on four levels (artist, brand owner, consumer and cooperation process).

Originality/value

This editorial and the entire special issue together represent the first anthology on the topic of the interface between brand management and arts. The collection and classification of the existing literature, the formulation of ideas for future research and the content of the seven papers are collectively excellent starting springboards for new and fresh brand research projects.
