Lean thinking to change healthcare organisations: a case study to reduce waste and redesign services
No full textIn the healthcare environment, quality systems have already provided significant results in organising procedures and human resources. However, the lack of managerial methodologies and knowledge sharing regarding best practices has limited the positive effects from new research and limited achievements. The lean approach can change healthcare organisations that adopt continuous improvement logics and can create substantial business results. This paper focuses on the development and application of lean principles in an oncology unit to increase the service performance levels while following and reducing waste, time, and non-value added activities. The study aims at improving healthcare processes within an oncology department, dealing with four types of cancer: breast, lung, head and neck, and gastric. The five principles of lean thinking were applied to identify the value from a patient's perspective and to follow the value stream. To achieve these ambitious goals, both basic lean tools and advanced techniques were implemented

Lean Six Sigma : la nuova frontiera per la qualità
No full textLa globalizzazione dei mercati ha imposto alle aziende standard qualitativi dell’output offerto sempre più elevati. Fattori quali la qualità, la rapidità e le modalità di consegna sono diventati sempre più determinanti per il successo di un’azienda. Ecco sorgere l’esigenza di implementare metodi di miglioramento continuo, capaci di incrementare la business performance di una realtà industriale, attraverso tecniche di problem solving.
La metodologia Lean Six Sigma, o LeanSigma, è attualmente l’arma più efficace per rispondere alla dinamicità del mercato ed offrire un prodotto competitivo.
Il presente testo si pone l’obiettivo di fornire al lettore le linee guida essenziali per sviluppare un progetto Lean Six Sigma in azienda.
Il Lean Six Sigma è una strategia manageriale di miglioramento continuo che si focalizza sulla qualità di prodotto e sulla velocità di processo. Nasce dalla sinergia di due metodi: il Six Sigma e la Lean Production, che negli ultimi anni hanno contribuito alla svolta nella gestione dei processi industriali. Il Six Sigma si focalizza sulla variabilità, riducendo la difettosità di processo, la Lean Production contribuisce a tagliare sprechi, migliorando l’utilizzo delle risorse e dei tempi di ciclo. Applicando il LeanSigma è possibile rivoluzionare le prestazioni d’efficienza in ogni area aziendale, sia a livello strettamente produttivo, che per quanto riguarda i processi transazionali, creando in azienda la consapevolezza dell’importanza di un modo nuovo di agire e di concepire il miglioramento continuo.
Un progetto LeanSigma si struttura in cinque fasi (define, measure, analyse, improve, control) nella quali ogni passaggio logico ha una sua motivazione e costituisce una vera e propria filosofia da seguire per ap-profondire e dipanare un’analisi di miglioramento a qualunque livello di dettaglio.
Il testo propone un approccio strutturato alla metodologia, definendo il percorso d’implementazione in azienda attraverso strumenti ed esempi pratici
Six Sigma methodology: an effective tool for quality management.
No full textThe quality standards of the output, the features of delivery and the
introduction of new services are becoming the most important factors to
success in business performance. In this context, the application of new
methodologies is essential to increase the business performance. Six Sigma can
give an important solution for those companies that intend to highlight the
customer satisfaction focusing on the continuous improvement of the processes.
The purpose of this paper is to show the power of the Six Sigma methodology
in increasing the performance level of industrial processes and systems.
The paper shows a Six Sigma case study applied to the automotive market
Design and Experimental validation of a Shape Memory Alloy actuator for Linear Motors
No full textThis paper presents an innovative mechanical actuator using a shape memory alloy (SMA) with a cooling system based on combined thermoelectric effect and forced air cooling systems. The main advantages of using SMAs include the reduction of the system weight, the ease and reliability in application, and a simple control strategy. This study focuses on the development of the system highlighting the mathematical model of the actuator, and an experimental prototype was implemented. Several experiments are used to validate the model and to identify best SMA actuator configuration parameters. Experiments were used to evaluate the actuator closed-loop performance, stability, and robustness properties
CMM Measurement Variability Analysis: a Comparison Between Two Metrological Laboratories Measuring Three Industrial Workpieces
No full text
Analysis of the variability of cutting processes when many factors are perturbed.
Full text linkSince the knowledge of industrial processes is mainly based on virtualisation, it is fundamental to develop a better understanding of the real processes performing analysis from an industrial point of view. Every analysis must use tools and solutions that could be really useful for industries, and become improvement keys for success. This paper shows a structured analysis of a turning process, to gain useful information, to evaluate experimental data and to define some improvement guidelines. On the basis of an excellent dataset, the main objective is to perform statistical analyses to estimate the influence of critical factors on response variables
