Improving the Production Efficiency Based on Algorithmization of the Planning Process

Planning and managing the production process are key challenges faced by every manufacturing organization. The main contribution of this article lies in the analysis and design of a planning algorithm that takes into consideration the specifics of this environment. The proposed algorithm encompasses elements of batch production, including a just-in-time approach. The article focuses on scenarios within batch production. Managers of manufacturing and supply companies must ensure smooth fulfillment and uninterrupted production of the agreed-upon quantity of parts. However, this task presents complex challenges. The product portfolio requires meticulous sequencing of production batches, and subsequent parts need to be temporarily stored in their raw state for further processing. Moreover, product variability necessitates frequent adjustments to the production line, resulting in delays. Shortages in manpower additionally place demands on shift organization. The company’s primary objective is to increase production efficiency while simultaneously reducing inventory and minimizing non-standard shift work. The challenge was to reconcile seemingly conflicting company requirements and to concentrate on solutions with swift implementation and minimal costs. Ensuring seamless production operation can be addressed by expanding supporting technologies or by increasing production capacity, such as acquiring an additional production line. However, these options entail costs and do not align with the company’s expectation for immediate impact and cost savings. However, improving production efficiency can also be achieved by altering the approach to production planning, which is the central theme of this article. The key element is ensuring that the customer plan is adhered to while working with a fixed production logic and variable input factors that must account for various non-standard situations.

MP33-10 INCREASED GENITOURINARY CANCER INCIDENCE AND LOWER TESTOSTERONE LEVELS ARE FOUND IN MEN PERFORMING NON-STANDARD SHIFT WORK

This work schedule is defined as working outside of the normal 7am-6pm hours. Additionally, past literature have shown a marked correlation between sleep deprivation and cancer risk, prompting us to investigate the relationship between NSSW schedules and cancer. The objective of this study is to explore the impact of NSSW schedules on the incidence of cancer as well as its impact on urologic markers. METHODS: A retrospective chart review was conducted, having identified over 3000 patients from the electronic medical records of a university hospital. The accrued patient cohort included both those who were involved in NSSW schedules and those who were not. The database was then linked to the Texas Cancer Registry to identify which of these patients have had a documented cancer diagnosis since 1995. The data from the registry included the age of cancer diagnosis, primary site, histology type, and metastatic status. The statistical analyses were performed using SPSS software. RESULTS: The statistical analysis revealed that the average age of cancer diagnosis is more than six years younger in NSSW versus those with regular work schedules. Similarly, non-standard shift workers experienced higher levels of prostate-specific antigens (4.942 ng/mL vs. 1.204 ng/mL). As expected from previous studies, non-standard shift workers faced significantly lower levels of endogenous testosterone (358.6 ng/dL vs 618.6 ng/dL). Furthermore, the NSSW population’s incidence of cancer is roughly double the age-adjusted cancer incidence rate of men in Texas. Of the NSSW who had a cancer diagnosis (n=45), the most common cancer primary sites were the male genital organs (n=16), the urinary tract (n=5), and the hematopoietic and reticuloendothelial systems (n=5). CONCLUSIONS: Our study has demonstrated that NSSW are at higher risk of developing cancer than the general male population. NSSW who already represent a clinically vulnerable population, may be somewhat immunocompromised as evidenced by their increased cancer incidence. The increased incidence of urogenital cancers within the NSSW group emphasizes the greater need of urologic focus for these men in clinical practice.

Shift Work Sleep Disorder and Night Shift Work Significantly Impair Erectile Function

ObjectivesHere we examine the association between shift work sleep disorder (SWSD) and erectile dysfunction (ED) in shift workers. MethodsMen presenting to a single andrology clinic between January 2014 and July 2017 completed validated questionnaires: International Index of Erectile Function (IIEF), Patient Health Questionnaire-9 (PHQ-9), and the nonvalidated SWSD Questionnaire. Men were also asked about shift work schedule, comorbidities, phosphodiesterase 5 (PDE5) inhibitor use, and testosterone use. Serum total testosterone values were determined for each visit. Linear regression was performed controlling for testosterone use, testosterone levels, PDE5 inhibitor use, age, and comorbidities to determine the effect of SWSD on ED as assessed using the IIEF. ResultsOf the 754 men completing questionnaires, 204 reported nonstandard shift work (begins before 7 am or after 6 pm, regularly extends out of that frame, or rotates frequently) and 48 were found to have SWSD using a screening questionnaire. Nonstandard shift work alone did not result in worse IIEF-EF scores (P = .31), but those who worked nonstandard shifts and had SWSD demonstrated IIEF-EF scores 2.8 points lower than men without SWSD (P < .01). When assessing for the type of shift work performed, men who worked night shifts had IIEF-EF scores 7.6 points lower than men who worked during the day or evening (P < .01). Testosterone use improved IIEF-EF scores for men with SWSD by 2.9 points, ameliorating the effect of SWSD on ED. However, baseline testosterone levels were not associated with worse erectile function in this cohort. ConclusionMen with SWSD have worse erectile function, with men who work night shifts having even poorer erectile function. These findings suggest that circadian rhythm disturbance may significantly impact erectile function. While testosterone therapy may partly reverse the effects of SWSD, shift work is a potential risk factor for ED and should be assessed for as part of the evaluation of men with ED.Rodriguez KM, Kohn TP, Kohn JR, et al.

Increased Risk of Hypogonadal Symptoms in Shift Workers With Shift Work Sleep Disorder

To examine the association between shift work sleep disorder (SWSD), a primary circadian rhythm disorder characterized by excessive day-time sleepiness associated with shift work, and hypogonadal symptoms in shift workers. Men presenting to an andrology clinic between July 2014 and June 2017 completed questionnaires assessing shift work schedule, SWSD risk, and hypogonadal symptoms ([quantitative] Androgen Deficiency in the Aging Male [qADAM, ADAM]). The impact of nonstandard shift work and SWSD on responses to qADAM and ADAM was assessed using ANOVA and linear regression. About 24.1% (619/2571) of men worked nonstandard shifts. Of those, 196 (31.7%) were considered to have SWSD. Controlling for age, comorbidities, and testosterone (T) levels, nonstandard shift workers had qADAM scores 1.12 points lower than day-time workers (P <.01). Subgroup analysis of nonstandard shift workers showed that those with SWSD had qADAM scores 5.47 points lower than men without SWSD (P <.01). In this same subgroup analysis, SWSD was independently associated with lower T levels (mean decrease 100.4 ng/dL, P <.01) when controlling for age, comorbidities, and prior T supplementation. Nonstandard shift workers with SWSD have even worse hypogonadal symptoms and lower T levels than day-time workers and nonstandard shift workers without SWSD. This suggests that poor sleep habits, as identified by SWSD, may contribute to the more severe hypogonadal symptoms seen in nonstandard shift workers.

Shift Workers With Shift Work Disorder Have Worse Lower Urinary Tract Symptoms

ObjectiveTo examine the association between shift work or shift work disorder (SWD) and lower urinary tract symptoms (LUTS). Nonstandard shift workers are defined as those working shifts outside of a normal 7 AM-6 PM work day. MethodsMen presenting to a single andrology clinic between July 2014 and June 2017 completed questionnaires that included questions about work schedules, shift work status, SWD[1][1], personal well-being via the Patient Health Questionnaire-9, and LUTS (International Prostate Symptom Score [IPSS]). Men who had previously undergone prostate surgery were excluded. Shift work and SWD on IPSS was assessed via multivariate linear regression. ResultsOf the 2571 men who completed all questionnaires, 619 (24.1%) reported working nonstandard shifts in the past month. Of these, 196 (31.7%) had high risk of SWD as determined by a questionnaire. When controlling for age, medications, surgical intervention for benign prostatic hyperplasia, comorbidities, and testosterone (T) levels, nonstandard shift work overall was not associated with worse LUTS (P = .82). However, nonstandard shift workers at high risk for SWD had IPSS scores that were clinically significantly higher (3.74 points ± 0.57 standard error) than nonstandard shift workers without SWD (P <.0001). ConclusionNonstandard shift workers at high risk for SWD have worse LUTS than those without SWD. However, no association between nonstandard shift work and LUTS was found.

The Effect of Shift Work on Urogenital Disease: a Systematic Review.

Non-standard shift work schedules negatively impact the overall health of shift workers, and several studies have shown that shift work, specifically, is detrimental to urogenital health. The aims of this study are to systematically review the literature and determine the effect of shift work on the outcomes of hypogonadism, male infertility, lower urinary tract symptoms, and urogenital cancers. Recent evidence supports associations between non-standard shift work and an increase in the frequency of prostate cancer and the severity of erectile dysfunction, lower urinary tract symptoms, and hypogonadal symptoms, as well as worsening of semen parameters and fertility. These associations are strengthened by the presence of shift work sleep disorder (SWSD) which affects up to 20% of shift workers. No studies have assessed the impact of shift work on the frequency or severity of nephrolithiasis, interstitial cystitis, pelvic pain, prostatitis, or urinary tract infections. Non-standard shift work has been associated with a variety of negative health outcomes and urologic complications, especially with concurrent shift work sleep disorder. Recognition of these elevated risks among shift workers can aid in more effective screening for urologic conditions.

Men working non-standard shifts are at increased risk for shift work sleep disorder (SWSD), a primary circadian rhythm disorder characterized by excessive daytime sleepiness associated with shift work. Here we examine the association between SWSD and erectile dysfunction (ED) in shift workers.

Linear regression was performed controlling for testosterone use, testosterone levels, PDE5-inhibitor use, age, and comorbidities to determine the effect of SWSD on erectile dysfunction as assessed using the IIEF-EF. RESULTS Of the 2,571 men completing questionnaires, 1,952 reported non-standard shift work and 196 were found to have SWSD. 802 men completed the IIEF-EF questionnaire. Non-standard shift work alone did not result in worse IIEF-EF scores (p = 0.31), but men with SWSD had IIEF-EF scores that were 2.8 points lower than men without SWSD (P<0.01). When assessing for the type of shift, we found that men who worked night shifts had IIEF-EF scores 7.58 points lower than men who worked during the day or evening (p < 0.01). Testosterone use improved IIEF-EF scores for men with SWSD by 2.90 points, ameliorating the effect of SWSD. Testosterone levels were not associated with worse erectile function. CONCLUSIONS Men with SWSD have statistically and clinically worse erectile function, and men who work night shifts have even worse ED. These findings suggest that circadian rhythm disturbance may significantly impact erectile function. Testosterone therapy may partly reverse the effects of SWSD.

The Relationship Between Shift Work and Men's Health.

More than 21 million Americans and nearly 20% of the U.S. workforce are shift workers. Non-standard shift work, defined as work that falls outside of 6 am-6 pm, can lead to poor diet, exercise, and sleep habits that lead to decreased productivity, increased workplace accidents, and a variety of negative health outcomes. To investigate the associations between shift work exposure and chronic medical conditions such as metabolic syndromes, cardiovascular disease, gastrointestinal disturbances, and depression as well as urologic complications including hypogonadism, male infertility, lower urinary tract symptoms, and prostate cancer with a focus on the effects of shift work sleep disorder (SWSD) on the severity of these negative health outcomes. We reviewed the literature examining effects of shift work and SWSD on general and urologic health. We produced a summary of effects of shift work on health with focus on the increased risk of negative health outcomes in non-standard shift workers, particularly those with SWSD, when compared to daytime workers or workers without SWSD. Studies have associated non-standard shift work schedules and poor health outcomes, including increased risks of diabetes mellitus, dyslipidemia, hypertension, heart disease, peptic ulcer disease, and depression, in shift workers. However, few studies have focused on the role that shift work plays in men's urologic health. Current evidence supports associations between non-standard shift work and increased hypogonadal symptoms, poor semen parameters, decreased fertility, lower urinary tract symptoms, and prostate cancer. These associations are strengthened by the presence of SWSD, which affects up to 20% of shift workers. Unfortunately, interventions, such as planned naps, timed light exposure, melatonin, and sedative hypnotics, aimed at alleviating excessive nighttime sleepiness and daytime insomnia in non-standard shift workers experiencing SWSD, are limited and lack strong evidence to support their efficacy. Non-standard shift work has been associated with a variety of negative health outcomes and urologic complications, especially with concurrent SWSD. Recognition of these increased risks among shift workers can potentially aid in more effective screening of chronic health and urologic conditions. Non-pharmacologic treatment of SWSD focuses on behavioral therapy and sleep hygiene while melatonin, hypnotics, and stimulants are used to alleviate insomnia and excessive sleepiness of SWSD. Further research into both pharmacologic and non-pharmacologic therapies for SWSD is needed to establish more definitive guidelines in the treatment of SWSD in order to increase productivity, minimize workplace accidents, and improve quality of life for shift workers.

Poor Sleep Quality Predicts Hypogonadal Symptoms and Sexual Dysfunction in Male Nonstandard Shift Workers

To investigate the impact of sleep quality in hypogonadal symptoms and sexual function in men working nonstandard shifts. Men treated at a single andrology clinic between July and October 2014 completed questionnaires assessing sleep quality, hypogonadal symptoms (Androgen Deficiency in the Aging Male [ADAM/qADAM]), and sexual function (International Index of Erectile Function [IIEF]). Serum hormone levels were assessed at the time of survey completion. One hundred eighty-two men were identified as working nonstandard shifts (work that starts before 7 a.m. or after 2 p.m., rotates, or regularly includes hours outside of the standard 7 a.m. to 6 p.m. workday) with a mean ± SD age of 41.1 ± 10.8 years. Of men working nonstandard shifts, those with better sleep quality had fewer hypogonadal symptoms and better sexual function. Multivariate regression analysis revealed significant linear associations between sleep quality and qADAM score (P = .008), positive ADAM responses (P = .003), and IIEF score (P = .0004). When comparing individual groups, men who were "very satisfied" (n = 60) with sleep quality had higher qADAM scores than men who were "somewhat dissatisfied" (P = .02), and men who were "very dissatisfied" had significantly lower IIEF scores than men who were "very satisfied" (P = .001) and "somewhat satisfied" (P = .005). No associations between sleep quality and mean serum testosterone, free testosterone, estrogen, dehydroepiandrosterone, follicle-stimulating hormone, and luteinizing hormone levels were observed. Men who work nonstandard shifts and have poor sleep quality are at increased risk for hypogonadal symptoms and sexual dysfunction.

Parental Work Schedules and Child Overweight or Obesity: Does Family Structure Matter?

The authors used longitudinal data from the Fragile Families and Child Wellbeing Study (N = 5,482) to investigate whether maternal and paternal work schedules affect child overweight or obesity. They took the novel step of examining whether this effect is consistent for children living in different family structures. Findings from child fixed effects models suggest that the probability of child overweight or obesity was higher for children living with mothers who worked standard shifts at a primary job and nonstandard shifts at a secondary job compared to children living with mothers who worked a standard shift at a primary job only. Fathers' work schedules were not associated with child overweight or obesity. Unexpectedly, maternal standard shift work at a primary job and nonstandard shift work at a secondary job was associated with overweight or obesity only among children living with married biological parents.

Similarly, men who work non-standard shifts are also prone to worse sleep quality and its sequelae. Here we assess the risk of LUTS in men working non-standard shifts. METHODS Men presenting to a single andrology clinic between July and October 2014 were given the International Prostate Symptom Score (IPSS) and asked whether they worked non-standard shifts, defined as ‘starting before 7 am or after 2pm, rotating, or regularly including hours outside of the standard 7 am to 6 pm work day.’ Men were also asked to rate various aspects of their sleep on a 4-point Likert scale for each of 11 questions. Serum testosterone (T) levels were measured at the time of survey completion. We compared IPSS scores, ages, and serum T levels between men as a function of sleep quality using ANOVA and independent sample t-test. RESULTS Of the men presenting to clinic, 849 completed the survey and 239 (28%) reported non-standard shift work and were included for further analysis. Men working non-standard shifts had a mean±SD age of 42±11 (range 21-76) years. Of men working non-standard shifts, those who reported problems falling asleep had worse LUTS than those who did not (IPSS score 9 vs. 6, p < 0.001); there were no differences in age (43 vs. 41 years old, p = 0.075) or T levels (636 vs. 605 ng/dl, p = 0.606) between these groups. Men who had difficulties staying asleep had more severe LUTS (IPSS score 6 (‘No Problem,’) vs. 13 (‘Serious Problem’), p = 0.004) as did those who were unable to fall back asleep after awakening (IPSS score 5 (‘No Problem’) vs. 13 (‘Serious Problem’), p < 0.001), with no difference in age (p=0.304) or serum T levels (p=0.080) between groups. Worse LUTS were also observed in men reporting a decreased sense of wellbeing (IPSS score 6 (‘Normal’) vs. 9 (‘Very Decreased’), p < 0.001) and those with decreased physical/mental function (IPSS score 6 (‘Normal’) vs.10 (‘Very Decreased’), p = 0.016), with no difference in age (p=0.393) or serum testosterone (p=0.345). CONCLUSIONS Men working non-standard shifts who have difficulty falling asleep, staying asleep, and falling back asleep report more severe LUTS than men who do not have similar sleep difficulties. Similarly, men who report a decreased sense of wellbeing and decreased physical or mental function as a result of their shift work also have more severe LUTS. These findings implicate sleep quality as a risk factor for LUTS symptom severity, arguing for optimization of sleep habits in men generally, and particularly those with pre-existing LUTS. © 2015 by American Urological Association Education and Research, Inc.FiguresReferencesRelatedDetails Volume 193Issue 4SApril 2015Page: e832 Advertisement Copyright & Permissions© 2015 by American Urological Association Education and Research, Inc.MetricsAuthor Information Alexander W.

Associations Between Employees’ Work Schedules and the Vocational Consequences of Workplace Injuries

This study examines the effect of long-hour work schedules and nonstandard shift work (e.g., night and evening shifts) on the ability of injured workers to maintain productive employment following a workplace injury. Analyses were based on 13 years of data from the National Longitudinal Survey of Youth. Multivariate logistic regression analyses were performed with one of ten nonstandard schedules as the independent variable and a particular vocational consequences as the dependent variable. Vocational consequences included being unable to perform normal job duties, temporary job reassignment, working less than full time, filing a workers' compensation claim, and quitting or being fired because of the injury. Covariates in the regression model included age, gender, occupation, industry, and region. The most prominent effects of working a nonstandard schedule were a increased risk of being fired (OR = 1.81; 1.15-2.90 CI 95%), quitting (OR = 1.68; 1.20-2.36 CI 95%), or being unable to work full time (OR = 1.33; 1.08-1.64 CI 95%) following an injury, compared to injured workers in conventional schedules. Schedules involving overtime and long working hours generally had a greater impact on vocational consequences following a workplace injury than did schedules involving night, evening, and other nonstandard shift work. Occupational rehabilitation professionals need to consider the specific type of work schedule when developing effective return-to-work plans for injured workers. Special precautions need to be taken for workers returning to schedules that involve more than 12 h per day, 60 h per week, and long commutes.
