A Study on the Use of Performance Indicators in Project Monitoring of Reinforced Concrete Structures Design (pp. 191-198)

Andre Luiz Aquere, Cristiana Sales Marques da Cruz Oliveira
A critical factor that determines the success of any continuous improvement process is the ability to quantitatively measure performance. After all, it is difficult to understand, manage, or improve parameters that cannot be quantitatively measured; with the aim of providing concrete structure designers with a design performance monitoring tool, this paper presents performance indicators focused on material consumption for the building concrete structures design. The proposed indicators were applied to building projects provided by structural designers in Brasilia, Brazil, and focused on the structural typology of buildings in the Águas Claras neighborhood. To apply the performance indicators, the buildings were grouped according to the structural solution adopted in the project making possible to analyze the influence the structural solution has on the consumption of concrete and steel materials. Finally, the obtained values were compared with benchmark values from previous studies as well as with values from a building designed in accordance with a new version of the Brazilian concrete design technical standard. In the end, this paper improves the knowledge on the influence of design decisions on the consumption of raw materials in building concrete structures and it provides the structural designers with a tool set to monitoring their projects performance.

Sustainable Work Environment with Lean Production in Textile and Clothing Industry (pp. 183-190)

Laura C. Maia, Anabela C. Alves, Celina P. Leao
The objective of this paper is to discuss Lean Production (LP) as a work organizational model that fosters a sustainable work environment in the companies. This is achievable through some Lean tools and initiatives that, when applied to the work environment reduces the energy, water consumption, environmental waste and raw-materials consumption and improves leanness and agility. This paper focuses the Textile and Clothing Industry (TCI) and brings up proposals, initiatives and/or projects that are related with Lean Production aims. Traditionally, TCI had been greatly dependent on natural resources: natural fibers, dyes, water, energy among others and a high consumer of water and energy, especially in dyeing and finishing processes. At the same time, these processes have a water and soil pollution problem. In this manner, reduce the consumption of these resources and reduce pollutants should be a major concern for companies and individuals to achieve a sustainable development. In this paper, the authors also present some proposals of how companies may engage in such projects.

Home Health Care Logistics Management: Framework and Research Perspectives (pp. 173-182)

E. Valentina Gutiérrez, Valentina Gutiérrez, Carlos J. Vidal
Home Health Care (HHC) services are a growing sector in the medical service business. These services are based on a delivery network in which patients are hospitalized at their homes and health care providers must deliver coordinated medical care to patients. The fact that patients and medical staff's homes are considered as a component of the delivery network creates a difference from typical health care organizations and generates a greater complexity on logistics decisions. In this paper we provide a reference framework for HHC logistics management in order to identify research perspectives in the field. With this framework we present a brief review of the current literature in models and methodologies used to support logistics decisions and identify research gaps. In particular, we emphasize the need to develop and implement more integrated methodologies to support decisions at tactical and strategic planning levels and to consider key features from real systems.

Using the Clearing Function to evaluate the Pricing Capacity of Resources at Low Levels of Utilization in Production Planning (pp. 161-172)

Raimundo J. B. de Sampaio, Wenyu Sun, Rafael R. G. Wollmann
It is well known from the daily industrial experience that high levels of throughput in production depend on high levels of work–in–process or releases into the system, and that high levels of work–in–process may increase the total lead time into the systems, decreasing expected revenues. This clearly suggests that sometimes increasing production capacity is in our best interest even before it becomes tight, even though the necessary information for accomplishing this is not provided by most of the approaches used for these issues, and in particular, by classical linear programming models. Recently some authors developed a framework to circumvent this drawback in the approach of linear programming based on the concept of clearing function that strives, together with the approach of linear programming, to allow for the pricing of low levels of capacity utilization. Nevertheless, the resulting new model was not treated directly but approximated by a linear model, which received a classical treatment, revealing very little news. In this paper we treat this new model directly, and furthermore, we took a new approach for the linear model, which in our view, has produced a new and deeper vision for the subject.

An Overview of Road Cargo Transport in Brazil (pp. 151-160)

Maria da Penha Araujo, Vania Barcellos Campos, Renata Albergaria Bandeira
This study aims to evaluate the operation of the main actors in the Brazilian market of road freight transportation: owner operators and carrier companies. It initially presents an overview of cargo transportation in Brazil, highlighting its characteristics and freight market. Subsequently, in order to characterize the performance of owner operators and carrier companies, a survey is conducted with carriers that act in Sao Paulo – Rio de janeiro. The result of this research enabled us to identify conditions of the fleet and freight costs, besides allowing a comparison between the operation of owner operators and carrier companies.
