Abstract

Purpose

The purpose of this paper is to study the relationships between the capabilities and performance characteristics of logistic service providers (LSPs) in the Caribbean region. The study considers the organization’s process improvement (PI) performance as it relates to their innovation capabilities, their efforts into information sharing and collaboration with customers, their planning for contingencies and considering the uncertainty of their customer’s technology.

Design/methodology/approach

A survey was applied to 88 LSP firms with operations in the Caribbean region. Structural equation modeling was used to analyze the hypothesized relationships.

Findings

The results indicate that the PI performance of LSPs is significantly related to their innovation capabilities, and that these capabilities are positively related to collaboration and exchange of relevant information. Furthermore, they indicate that information sharing between LSPs and their customers significantly improves the quality of contingency planning. However, the study showed that innovation capabilities are not directly related to the LSPs’ focus on contingency planning and that customers’ technology uncertainty does not have a significant effect on the LSPs’ innovation capabilities.

Research limitations/implications

The sample of LSP firms is limited to three countries of the Caribbean region. Further examination of the model in additional countries and across multiple industrial contexts would increase the validity of the findings and expand to settings such as manufacturing and services.

Originality/value

This study measures operational performance of LSPs from a different perspective: its PI performance, and considers how multiple factors affect this performance.

Propósito

El propósito de este trabajo es estudiar las relaciones entre las capacidades y características de ejecutoria de los proveedores de servicios de logística (LSP) en la región del Caribe. El estudio considera la ejecutoria en la mejora de los procesos de la organización en relación con sus capacidades de innovación, sus esfuerzos en el intercambio de información y colaboración con los clientes, la planificación de contingencias y teniendo en cuenta la incertidumbre de la tecnología de sus clientes.

Diseño/metodología/enfoque

Se aplicó una encuesta a 88 empresas de servicios logísticos con operaciones en la región del Caribe. Un modelo de ecuaciones estructurales se utilizó para analizar las hipótesis propuestas.

Resultados

Los resultados indican que la ejecutoria en la mejora de procesos de los LSP se relaciona significativamente a sus capacidades de innovación, y que estas capacidades se relacionan positivamente con la colaboración y el intercambio de información. Además, los resultados indican que el intercambio de información entre los LSP y sus clientes significativamente mejora la calidad de la planificación de contingencia. Sin embargo, el estudio demostró que las capacidades de innovación no están relacionadas directamente a la planificación de contingencia y que incertidumbre relacionada con la tecnología de los clientes, no tiene un efecto significativo en las capacidades de innovación de las LSP.

Limitaciones de la investigación/implicaciones

La muestra de empresas LSP se limita a tres países de la región del Caribe. La examinación en otros países y en otros contextos industriales aumentaría la validez de los resultados y ampliaría este a otras áreas como la manufactura y los servicios.

Originalidad y valor

Este estudio mide la ejecutoria operacional de los LSP desde una perspectiva diferente: su ejecutoria en la mejora de procesos y considera cómo múltiples factores afectan esta ejecutoria.

Abstract

Purpose

The focus of this paper is on reliability and availability design goals. It aims to provide top‐level estimates of the safety and maintainability of future spacecraft systems.

Design/methodology/approach

The developed design tool uses basic reliability principles to estimate the probability of a safe mission and the need for repairs/replacement during ground processing, before launch and start of mission, based on the characteristics of the vehicle's main systems: the number of subsystems, the mean time to repair, and the per subsystem average reliability.

Findings

A simple reliability, maintainability and safety model is developed to support the top‐level design process of future space transportation vehicles. It also describes how the developed design tool uses various sensitivity analysis functions to improve design decisions.

Originality/value

The goal of the developed tool is to provide engineers/vehicle developers during the early stages of design with a tool that demonstrates the effect on maintainability of improving component reliability and reducing the number of components.

Abstract

Current studies indicate that buyers can improve lead‐time performance and reduce total inventory‐system costs by splitting orders between two suppliers. These studies, however, treat transportation only implicitly as an element of the cost of placing an order. This is an important limitation, because shipping costs increase disproportionately as the size of shipment decreases and typically comprise a sizeable portion of total logistics cost. Investigates the role of transportation in the decision to procure from either one or two suppliers. A state‐of‐the art model was first modified to treat transportation costs explicitly and then used to conduct 54 experiments to measure the gains or losses in total logistics costs under a variety of representative conditions.
