Abstract

Purpose

Traditional algorithms require at least two complete vector observations to estimate orientation parameters. However, sensor faults and disturbances may cause some components of vector observations unavailable. This paper aims to propose algorithms to realize orientation estimation using vector observations with one or two components lost.

Design/methodology/approach

The fundamental of the proposed method is using norm equation and dot product equation to estimate the lost components, then, using an improved TRIAD to calculate attitude matrix. Specific algorithms for one and two lost components cases are constructed respectively, and the nonuniqueness of orientation estimation is analyzed from a geometric point of view. At last, experiments are performed to test the proposed algorithms.

Findings

The loss of components results in the loss of orientation information. The introduction of the norm equation and dot product equation can partially compensate for the loss of information. Experiment results and analysis show that the proposed algorithms can provide effective orientation estimation, and in vast majority of applications, the proposed algorithms can provide a unique solution in one lost component case and double solutions in two lost components case.

Originality/value

The proposed method addresses the problem of orientation estimation when one or two components of vector observations are unavailable. The introduction of the norm equation and dot product equation makes the calculation cost low, while the analyses from a geometric point of view makes the study of nonuniqueness more intuitive.

Abstract

Purpose

Current research efforts exhibit a surge imperative for a building information modelling (BIM) approach that embodies a repository of all relevant data of existing building components while monitoring and consistently recording numerous components’ functions throughout its lifecycle, especially in Egypt. This research paper aims to develop an integrated as-is BIM-facility management (FM) information model for the existing building’s components via a case study, depicting a repository for historical data and knowledge amassed from inspections and conveying maintenance decisions automatically during the FM practices.

Design/methodology/approach

The developed approach pursues four successive steps: data acquisition and processing of building components; components recognition from point clouds; modelling scanned point clouds; and quick response code information transfer to BIM components.

Findings

The proposed approach incorporates the as-is BIM with the building components’ as-is FM information to portray a repository for historical data and knowledge collected from inspections to proactively benefit facility managers in simplifying, expediting and enhancing maintenance decisions automatically during FM practices.

Originality/value

This paper presents a digital alternative to manual maintenance recordkeeping concerning building components to retrieve their as-is and historical data using a case study in Egypt. This paper proposes a broad scan to as-is information BIM approach for the existing building’s components to condone maintenance interventions using a versatile, affordable, readily available and multi-functional method for scanning the building’s components using a handheld tool.

Abstract

This study proposes targeted modernization of the Department of Defense (DoD's) Joint Forces Ammunition Logistics information system by implementing the optimized innovative information technology open architecture design and integrating Radio Frequency Identification Device data technologies and real-time optimization and control mechanisms as the critical technology components of the solution. The innovative information technology, which pursues the focused logistics, will be deployed in 36 months at the estimated cost of $568 million in constant dollars. We estimate that the Systems, Applications, Products (SAP)-based enterprise integration solution that the Army currently pursues will cost another $1.5 billion through the year 2014; however, it is unlikely to deliver the intended technical capabilities.

Abstract

Rather than organize as traditional firms, many of today’s companies organize as platforms that sit at the nexus of multiple exchange and production relationships. This chapter considers a most basic question of organization in platform contexts: the choice of boundaries. Herein, I investigate how classical economic theories of firm boundaries apply to platform-based organization and empirically study how executives made boundary choices in response to changing market and technical challenges in the early mobile computing industry (the predecessor to today’s smartphones). Rather than a strict or unavoidable tradeoff between “openness-versus-control,” most successful platform owners chose their boundaries in a way to simultaneously open-up to outside developers while maintaining coordination across the entire system.

Abstract

Purpose

The paper provides an overview of research published in the innovation and operations management (IOM) literature on 15 methods for cost management in new product development, and it provides a comparison to an earlier review of the management accounting (MA) literature (Wouters & Morales, 2014).

Methodology/approach

This structured literature search covers papers published in 23 journals in IOM in the period 1990–2014.

Findings

The search yielded a sample of 208 unique papers with 275 results (one paper could refer to multiple cost management methods). The top 3 methods are modular design, component commonality, and product platforms, with 115 results (42%) together. In the MA literature, these three methods accounted for 29%, but target costing was the most researched cost management method by far (26%). Simulation is the most frequently used research method in the IOM literature, whereas this was averagely used in the MA literature; qualitative studies were the most frequently used research method in the MA literature, whereas this was averagely used in the IOM literature. We found a lot of papers presenting practical approaches or decision models as a further development of a particular cost management method, which is a clear difference from the MA literature.

Research limitations/implications

This review focused on the same cost management methods, and future research could also consider other cost management methods which are likely to be more important in the IOM literature compared to the MA literature. Future research could also investigate innovative cost management practices in more detail through longitudinal case studies.

Originality/value

This review of research on methods for cost management published outside the MA literature provides an overview for MA researchers. It highlights key differences between both literatures in their research of the same cost management methods.

Abstract

Purpose

Multiteam systems (MTSs) have been employed across numerous organizations and occupations (e.g., healthcare, emergency disaster response, business, and military) to achieve complex goals over time. As MTSs are inherently different than team level and organizational level theories, this chapter highlights the defining features of these dynamic systems through a temporal lens. Thus, the main purpose of our chapter is to address the challenges and issues concerning MTSs over time in order to provide a future agenda to guide researchers and practitioners.

Methodology/approach

To explore temporality throughout this chapter, we leverage two key MTSs frameworks along with contributions from the literature to produce a review, which demonstrates the extent of MTS theoretical and practical findings. After reviewing the definitional components of MTSs, we highlight various compositional, linkage, and developmental attributes that operate within a system. We then expand upon these attributes to consider the structural features of the system that enhance boundaries between component teams (i.e., differentiation) and may disrupt the system over time (i.e., dynamism).

Findings

After reviewing and integrating current MTS literature, we provide a new conceptual framework for MTSs and their temporal complexities. We offer several methodologies that managers and researchers can employ to assess these complex systems and suggest practical recommendations and areas for future research as we continue to study MTSs.

Originality

Our original conceptual framework considers MTSs through a dynamic lens developing over time and suggests the need for future research to build upon this perspective.

Abstract

In this paper, we seek to understand how changes in product architecture affect the innovation performance of firms in a complex product ecosystem. The canonical view in the literature is that changes in the technological dependencies between components, which define a product’s architecture, undermine the innovation efforts of incumbent firms because their product development efforts are built around existing architectures. We extend this prevailing view in arguing that component dependencies and changes in them affect firm innovation efforts via two principal mechanisms. First, component dependencies expand or constrain the choice set of firm component innovation efforts. From the perspective of any one component in a complex product (which we label the focal component), an increase in the flow of design information to the focal component from other (non-focal) components simultaneously increases the constraint on focal component firms in their choice of profitable R&D projects while decreasing the constraint on non-focal component firms. Second, asymmetries in component dependencies can confer disproportionate influence on some component firms in setting and dictating the trajectory of progress in the overall system. Increases in such asymmetric influence allow component firms to expand their innovation output. Using historical patenting data in the personal computer ecosystem, we develop fine-grained measures of interdependence between component technologies and changes in them over time. We find strong support for the empirical implications of our theory.

Abstract

Purpose

Although the practice of multiteam systems (MTSs) has been around for decades, the science of these systems has only just begun. Within the past decade and a half, although much remains to be investigated, substantial progress has been made in breaking the surface of this research. The current volume provides a review of MTS case studies and the current chapter provides a synopsis of this research. The goal of this chapter is to identify how MTSs are operating under real-world conditions in order to bridge MTS science and practice.

Design/methodology/approach

In this chapter, the authors provide a case analysis of the presented MTSs in the current volume in order to identify issues innate to MTSs. An approach based on the SWOT analysis technique was utilized to identify strengths, weaknesses, threats, and opportunities of the identified MTSs. In addition, six lessons learned were extracted from a content analysis of the successes and failures of these MTSs.

Findings

Although MTSs may be unique to the environment in which they operate, there are several features which seem to be inherent to all. Strengths include possessing the ability to manage complex tasks and unexpected events, being flexible in nature, and integrating communication across levels. In opposition, weaknesses include the use of nontraditional communication patterns, challenges stemming from unit diversity and resources, and the lack of common training. Lessons learned from identified MTSs include (1) utilize effective communication; (2) establish shared mental models; (3) identify roles and responsibilities; (4) convey accountability and ownership; (5) consider the ramp-up period; and (6) train individuals in an MTS at multiple levels. Opportunities and threats to MTSs are also discussed in this chapter.

Originality/value

This chapter offers several contributions to the state of the field in regard to MTSs. The current chapter provides a detailed content analysis of several real-world MTSs. Characteristics inherent to MTSs are identified and discussed, and lessons learned are extracted. Traditionally, science and practice has focused on the presentation of lab-based MTSs; the current volume breaks new ground by identifying how MTSs operate “in the wild.” This chapter provides a summation of this volume and offers lessons learned for MTS researchers and those working within MTSs.
