Abstract

Purpose

The purpose of this paper is to present a case study in which data envelopment analysis (DEA) is used to evaluate and classify the suppliers of a Colombian motorcycle assembly company. This tool allows the integration of several attributes into single performance measures (cross-efficiency and diversity efficiency) and subsequent classification based on the values obtained for these two metrics.

Design/methodology/approach

The classification uses a methodology based on two main tools. The first is an input-oriented cross-efficiency DEA model with ordinal variables to evaluate the suppliers’ performance, and the second is a classification of these into categories that identifies those with good performance for features that make them outstanding.

Findings

The assembly company segments its suppliers according to supply frequency. The results show that suppliers working under a just-in-time system achieve superior performance with respect to other suppliers.

Practical implications

The application of this methodology in a real-world case illustrates how DEA can be a useful tool to support the evaluation and classification of suppliers (a process of increasing complexity given the current trend to include multiple strategic measures together with classical operational measures). Moreover, the methodology illustrated in the study can be adapted to other similar settings.

Originality/value

The main contributions of this paper are twofold. First, to the best of our knowledge, this is the first study to illustrate the use of DEA in a real case related to supplier evaluation. Second, the presence of ordinal variables (e.g. quality or environmental ratings) gives rise to DEA variants seldom used in this context.

Propósito

Este artículo presenta un caso de estudio en el que se utiliza análisis envolvente de datos (DEA) para evaluar y clasificar los proveedores de una ensambladora colombiana de motocicletas. Dicha herramienta permite integrar múltiples atributos en dos medidas de desempeño (eficiencia cruzada y de diversidad) y la posterior clasificación de éstos con base en los valores obtenidos para ambas medidas.

Diseño/metodología/enfoque

La clasificación usa una metodología basada en dos herramientas. La primera es un modelo DEA de eficiencia cruzada orientado a las entradas con variables ordinales que se usa para evaluar el desempeño de los proveedores. La segunda es una clasificación de los proveedores en categorías para identificar aquellos con buen desempeño en algunas características que los hacen sobresalientes.

Resultados

La compañía segmenta sus proveedores de acuerdo con la frecuencia de abastecimiento. Los resultados muestran que los proveedores que operan bajo justo a tiempo (Just-in-time, JIT) tienen un desempeño superior con respecto a los demás proveedores.

Implicaciones prácticas

La aplicación de esta metodología en un caso real ilustra como DEA es una herramienta útil para apoyar la evaluación y clasificación de proveedores (un proceso de complejidad creciente gracias a la tendencia actual de incluir medidas estratégicas junto a las medidas operacionales comúnmente utilizadas). Además, la metodología utilizada puede adaptarse fácilmente a otras situaciones similares.

Originalidad/valor

Las contribuciones de este artículo son dos. Primero, hasta donde sabemos, este es el primer estudio que ilustra el uso de DEA en un caso real de evaluación de proveedores. Segundo, la presencia de variables ordinales (por ejemplo, evaluaciones de calidad y medioambiente) resultan en modelos DEA que son poco utilizados en este contexto.

Abstract

Purpose

The purpose of this paper is to focus on the impact of trade openness and technology import on the change in demand structure of employment toward skilled workers. Because of the limited number of empirical papers done in the case of Tunisia, this research investigates whether these factors had similar effects on relative labor demand in Tunisia to those observed in the international literature.

Design/methodology/approach

For this purpose, the paper uses a manufacturing industries database provided by the Tunisian National Institute, the Quantitative Economic Institute and Comtrade of United Nations for six manufacturing industries. The methodology used here is a panel data technique, and consists of estimating a dynamic relative employment equation.

Findings

Empirical results show that trade liberalization and technology change positively affect relative employment of Tunisian manufacturing industries which confirms the existence of skill biased technological change that contributes to increase the relative demand for skilled workers.

Originality/value

The paper adds to existing literature by studying for the first time the case of Tunisian manufacturing industries by using dynamic model. The paper deals also with an econometrics issues related to the use of suitable estimation methodology in the case of dynamic panel data at macroeconomics level.
